October 2026

29 changes

Oct 12StudioFixed Audio-to-MIDI sometimes playing an extra click sound alongside a recognized drum hit when the model wrote the same hit twice.
Oct 9StudioFree and Starter plans can now buy extra credits (top-ups) directly, the same way paid plans already could.
Oct 9StudioFixed a clip's typed description sometimes not being saved yet when you immediately clicked Generate, so Generate could use an old or empty description.
Oct 8StudioStarting an Audio-to-MIDI upload now retries automatically if your connection drops or stalls, instead of failing outright.
Oct 8StudioRemoved the Ambiencer tool from Studio.
Oct 8APIFixed rare API requests failing with a generic error during brief backend routing hiccups — they now retry automatically or return a clear "try again shortly" response.
Oct 8APIRedesigned the API Playground: a cleaner layout with a request/response side panel, friendlier model names, a history of past generations you can revisit, and background video uploads so you can start your next run without waiting.
Oct 7StudioFixed the clip editor's version-picker popup sometimes appearing hidden behind the video, timeline, or sidebars.
Oct 7StudioThe Editor Assistant now shows you the sounds it's about to generate, with cost estimates, so you can pick which ones to make before anything is charged.
Oct 7StudioAudio-to-MIDI can now record directly from your microphone or capture your computer's own audio (like a song playing in another tab), with trimming before you submit.
Oct 7APISped up the developer API: every response returns about 0.6 seconds faster, v3 jobs report as finished about 2 seconds sooner, and video uploads begin processing roughly a second faster.
Oct 6StudioScore and sheet-music downloads that stalled partway through now retry automatically, with a manual retry option if that doesn't fix it.
Oct 6StudioFixed video thumbnails failing to generate for clips with legitimately black frames.
Oct 5StudioFixed new accounts created while connecting Mirelo to an AI assistant losing the link back to finish that connection — you were dropped onto the Studio home page with the assistant left unconnected.
Oct 5StudioFixed a generated clip sometimes restarting from the beginning or playing silently after you paused and pressed play again.
Oct 5APIFixed a batch of developer API bugs found during a production review: video and audio inputs are now validated and rejected with a clear reason before a job starts, not after; unsupported request methods and invalid or blocked videos get accurate error messages; response headers report correct concurrency and rate-limit numbers; a prompt-length check no longer wrongly rejects prompts containing emoji; a gap where a blank duplicate-request key silently skipped duplicate-request protection is closed; and video requests that ran past the end of a clip are no longer billed for more audio than they actually received.
Oct 5StudioFixed some short generations being charged one extra credit due to a floating-point rounding error.
Oct 3APIThe API Playground's video-to-SFX page now plays back your uploaded video with a toggle to switch between the original and generated sound, so you can compare them in context.
Oct 3APIFixed the API Playground's video comparison player sometimes freezing on one frame while comparing your original and generated audio — playback now waits for buffering instead of repeatedly jumping.
Oct 2StudioAudio-to-MIDI now recovers automatically from more transient network hiccups when starting or checking on a transcription job.
Oct 2APISound effects generated through the developer API now have a 7-day retention period, with deletion taking up to 14 days. API jobs and results are available for 24 hours, and download links can expire sooner — save your results as soon as they finish.
Oct 2PluginsDaVinci Resolve plugin 1.6.0 fixes stem generation: stems no longer freeze Resolve or get lost after being paid for, they land trimmed and faded at the correct volume instead of raw (previously sometimes about 18 dB too loud), and they're grouped onto a few named tracks instead of one new track per sound.
Oct 2PluginsDaVinci Resolve plugin 1.6.0 also fixes generating sound from a timeline range leaving your export settings and timeline markers changed afterward, and fixes the Extend/Inpaint tabs showing no clips when the timeline contained certain non-media audio items.
Oct 2WebsiteRedesigned Mirelo's public website for phones — tighter spacing, readable screenshots, a full-screen menu instead of nested accordions, a fixed Terms page that no longer scrolls sideways, and a notice that the editor currently needs a desktop browser.
Oct 1StudioFixed Studio showing a blank white screen while signing in — it now shows the app shell immediately and offers a retry or sign-out option if authentication takes too long.
Oct 1StudioFixed Audio-to-MIDI transcriptions occasionally being marked as failed during a brief backend hiccup, even though the job was still running and would have finished normally.
Oct 1APIFixed the Audio-to-MIDI API occasionally losing a finished synchronous result (and returning an error) when a brief backend hiccup happened right as the job completed — it now retries so you still get your result.
Oct 1APIFixed the v3 API not honoring a per-key concurrency-limit increase, which could cause rate-limit errors even after we raised a customer's limit.
Oct 1WebsiteAdded a Creator Partnership page (mirelo.ai/creators) for paid collaboration applications.

September 2026

124 changes

Sep 30StudioFixed clicking the timeline playhead (without dragging) jumping playback to the wrong time and stopping it.
Sep 30StudioFixed the editor sometimes playing silently, with no sound and no error, in Safari when another app was using your speakers — it now shows a notice and a way to recover.
Sep 30StudioUnified search, filters, and pagination across Studio's list pages, fixing three lists that previously stopped showing results after a fixed number of rows.
Sep 30StudioRemoved Studio's unused "project expires, restore by upgrading" messaging (the feature was never active) and clarified what deleting or removing a file actually does.
Sep 30APIThe API reference now opens on an overview page instead of dropping straight into one endpoint, and keeps the sidebar visible with working browser back and forward while you navigate.
Sep 29StudioFixed creating a video project from an audio-only file failing with a generic server error — Studio now catches this upfront and points you to Audio-to-MIDI.
Sep 29StudioFixed renaming an Audio-to-MIDI transcription with a long filename sometimes silently reverting to the old name.
Sep 29StudioFixed Audio-to-MIDI's metronome staying silent on iPhone due to an audio-timing error.
Sep 29APIThe Audio-to-MIDI API now offers a standalone instrument-detection endpoint, so integrations can get the same AI instrument suggestions Studio shows — detection is free when followed by a transcription.
Sep 29StudioFixed sign-up rarely completing when opened inside Instagram's or Facebook's built-in browser — email sign-up now comes first, since Google sign-in doesn't work in those browsers.
Sep 29StudioAudio-to-MIDI now detects copy-protected audio files at upload and explains why they can't be transcribed, instead of failing partway through with confusing errors.
Sep 29StudioMagic Mode's sound effects now default to a single combined track for new sessions instead of separated stems — you can still switch.
Sep 29StudioFixed the editor freezing or reloading itself after uploading a high-resolution video, caused by decoding too many timeline preview frames at once.
Sep 29StudioImproved keyboard accessibility across Studio (icon buttons, timeline drags, waveform handles) and stopped Gibberize from autoplaying its result with sound.
Sep 29StudioRedesigned the Profile and API keys settings pages for phones, with compact rows and an always-visible menu instead of a squeezed-down desktop layout.
Sep 29StudioFixed Google sign-in on Studio silently failing or looking stuck instead of showing an error you can retry from.
Sep 29StudioFixed video exports in Safari sometimes getting stuck indefinitely (often around 75%) with no file and no error message.
Sep 28StudioFixed Audio-to-MIDI occasionally marking completed, already-charged lyrics as failed and discarding them due to a timing conflict with the note transcription.
Sep 28StudioFixed sheet-music PDF preparation failing outright for songs whose triplets crossed a bar line after an irregular pickup measure.
Sep 28StudioFixed Studio's sign-in page staying blank with no message when required scripts failed to load — it now shows a clear error with a reload option and guidance.
Sep 28StudioFixed the Extender rejecting valid MP4, MOV, and some OGG files with an "Audio format not recognized" error.
Sep 28StudioFixed Audio-to-MIDI's instrument review getting stuck on "Audio preview unavailable" when a Windows computer's audio output failed — it now suggests checking your speakers and offers a retry.
Sep 28StudioFixed the editor saying an upload had failed while it was actually still in progress, which could lead you to delete a project that was uploading fine.
Sep 28StudioFixed Audio-to-MIDI's job list failing to load for accounts with many transcriptions, and not being searchable past the 100 most recent jobs.
Sep 28StudioFixed Audio-to-MIDI transcriptions occasionally failing outright due to an unrelated background scheduling hiccup right before the job started.
Sep 28APIThe v1 API now processes long videos in 60-second pieces for the 1.6 model (matching Studio and v2), instead of always using 10-second pieces, for fewer blended seams.
Sep 28ModelsFixed some Audio-to-MIDI drum transcriptions exporting hi-hat and tom hits as side-stick clicks in MIDI, sheet music, and playback, due to an outdated drum-mapping table for the current model.
Sep 28WebsiteFixed some marketing pages showing an error screen when background video autoplay was blocked by the browser.
Sep 26APIRestored the "Try it in the Playground" banner on each v3 API docs endpoint page.
Sep 25ModelsVoice transcriptions in Audio-to-MIDI can now play as a choir, a natural solo singer, or an electronic voice, with the AI suggesting a character from the source audio that you can change anytime, with loudness matched across all three options.
Sep 25PluginsFixed the plugins' and API's separated sound-effect stems losing very short sounds (like punches or clicks) on fast-cut footage — they're now preserved the way the web app already handles them.
Sep 25StudioAudio-to-MIDI can now transcribe lyrics for vocal tracks as a paid add-on — timed lyrics follow playback word by word and link to the notes being sung.
Sep 25StudioAudio-to-MIDI's lyrics now split Japanese, Chinese, and Korean words one character per note to match how those scores are written, instead of crowding a whole word under a single note.
Sep 25StudioLarge Audio-to-MIDI file uploads are now resumable — a dropped connection only re-sends the missing pieces instead of restarting the whole file from scratch.
Sep 25StudioFixed Studio crashing with a "Something went wrong" error for users with their browser's translate feature on, which mostly affected sign-up, sign-in, and Audio-to-MIDI for non-English speakers on iPhone.
Sep 25APIFixed video-to-SFX returning a generic server error for corrupt or undecodable video files — you'll now get a clear file-can't-be-processed message instead of repeated silent retries.
Sep 25StudioFixed Audio-to-MIDI's instrument-review screen showing "Audio preview unavailable" for AIFF files (which most browsers can't play) and some MP3s on Android — it now serves a browser-friendly preview copy.
Sep 25StudioFixed Audio-to-MIDI's Score view getting permanently stuck on "Couldn't render the score" after one failed attempt — opening Score now retries automatically, and a "Try again" button rebuilds without losing your edits.
Sep 25APIFixed the API's optimized MusicXML export falling back to the plain score for long pieces whose re-engraved file exceeded an overly conservative size limit.
Sep 25StudioFixed credit history mislabeling video-to-SFX generations as "Text to SFX" — it now shows "Video to SFX" to match what you actually used.
Sep 24APIThe v3 API reference is now shown to every visitor at /api-docs, including signed-out visitors and search engines, instead of only signed-in users.
Sep 24StudioFixed Audio-to-MIDI showing a misleading "stalled without detecting any notes" error when a transcription stalled after already finding notes.
Sep 24StudioFixed Audio-to-MIDI transcriptions failing immediately on an occasional transient "502 Bad Gateway" when starting — Studio now retries automatically.
Sep 24StudioFixed Audio-to-MIDI's original-audio playback showing "Original audio unavailable. Playing MIDI only." for about 5% of job opens, caused by a streaming link expiring before it was used.
Sep 24APIFixed the hosted MCP server rejecting agent platforms that can't do interactive sign-in — it now also accepts a Mirelo API key.
Sep 24WebsiteFixed Gibberize showing a generic error instead of clear guidance when a social video link was private, unavailable, or not a video.
Sep 23StudioFixed the Audio-to-MIDI metronome being silent in Chrome on Linux due to an incompatible click-sound format.
Sep 23APIThe developer API's video-to-SFX endpoint can now use the audio already inside your video to preserve existing dialogue, without needing you to extract and upload it as a separate file.
Sep 23StudioCustomers with personally billed Creator, Studio, Scale, or Business plans in EUR can now buy extra credits from the billing page, including during a trial.
Sep 23StudioAudio-to-MIDI's instrument picker is now a stable, searchable multi-select — choose several instruments without the menu closing or jumping after each pick.
Sep 23StudioFixed Audio-to-MIDI's Input–MIDI mix slider behaving incorrectly when the original recording failed to load — playback now switches cleanly to full MIDI instead.
Sep 23StudioFixed Studio suggesting you enable pay-per-use overage when running low on credits even if your account can't access that option — you'll now see relevant choices like buying credits or upgrading instead.
Sep 22StudioFixed Audio-to-MIDI's Score view failing to open on some lower-memory devices.
Sep 22StudioFixed Audio-to-MIDI's freshly uploaded audio preview sometimes disappearing if a background copy of the file failed to load.
Sep 22StudioFixed Audio-to-MIDI's Score view sometimes failing silently in Safari with no way to recover — it now retries automatically.
Sep 22ModelsAudio-to-MIDI now preserves triplets and swing rhythms in scores and exports instead of flattening them to straight notes, and you can select compound time signatures (6/8, 9/8, 12/8) when the music calls for it.
Sep 22PluginsThe Premiere, DaVinci Resolve, and REAPER plugins now show the same clear recovery guidance — enable overage, raise your limit, view plans, or contact support — when a generation can't be funded, instead of a disabled button or a dead-end error.
Sep 22StudioAudio-to-MIDI's instrument-detection step is noticeably faster.
Sep 21StudioFixed Command/Ctrl+A text selection in Studio input fields being invisible — it now shows the browser's native selection highlight.
Sep 21APISFX and Audio-to-MIDI API results now report which model release produced them, so you can tell exactly which model version generated a given output.
Sep 21StudioThe timeline's filmstrip now detects scene cuts and restarts at each one, so clicking a scene jumps the playhead straight to its start.
Sep 21ModelsAudio-to-MIDI now offers a realistic acoustic drum kit (the new default), accurately named electronic kits, and sound presets for instruments that previously had none — soloing a part in Score view also now produces a true single-part score.
Sep 18StudioFixed several Audio-to-MIDI playback bugs: Score's playhead no longer stalls, jumps backward, or lands on the wrong row when clicked; Restart now works immediately during playback; and selecting a later position no longer resets if the recording briefly buffers.
Sep 18StudioFixed some WAV files with unusual channel layouts failing to process for Audio-to-MIDI's instrument detection and audio preview.
Sep 18APIPublished a new API guide covering commercial use, attribution, and current operational limits for building products with Audio-to-MIDI and sound effects.
Sep 18StudioFixed dragging a new song onto an existing Audio-to-MIDI transcription skipping the upload consent and instrument-review steps.
Sep 18ModelsFixed Audio-to-MIDI sometimes adding an unnecessary empty pickup measure at the start of a score when a recording simply began with silence.
Sep 18StudioFixed an Audio-to-MIDI Pro output sometimes showing "Output not found" after deleting a different item from the list.
Sep 18StudioReplaced Audio-to-MIDI's fixed playback-mode picker with a single Input–MIDI mix slider that blends the original recording with generated MIDI in real time, and remembers your preferred balance.
Sep 18StudioFixed some Audio-to-MIDI performance-timed MIDI exports causing cut-off or missing notes in certain MIDI players.
Sep 18StudioAudio-to-MIDI now accepts recordings up to 30 minutes long, up from a shorter limit, in Studio and via the API.
Sep 18StudioAudio-to-MIDI now retries when sheet-music rendering is slow to start, giving the full score and PDF export another chance to load before falling back to simpler sheet music.
Sep 17StudioAudio-to-MIDI's export dialog now lets you choose exactly which instruments to include — any combination, not just the full mix or a single instrument — for MIDI, MusicXML, and audio exports, with everything selected by default.
Sep 17StudioAudio-to-MIDI's full scores and MIDI instrument sidebar now use the same, stable instrument order, so arrangements no longer get shuffled between transcriptions or between the two views.
Sep 17ModelsAudio-to-MIDI is now officially Audio-to-MIDI Pro — read what's new in our launch announcement and updated product page.
Sep 17StudioFixed Audio-to-MIDI's original-recording playback and stereo comparison failing to load on older versions of Chrome (109 and earlier).
Sep 17StudioFixed vocal (Lead and Aahs) instrument playback in Audio-to-MIDI being noticeably quieter than the rest of the arrangement.
Sep 17StudioFixed selected-range re-transcription in Audio-to-MIDI being unusable when started from Score view — it now switches to Piano Roll, where range selection lives, and stays there.
Sep 17StudioFixed Studio showing an unusable credit balance when credit provisioning was still catching up — affected accounts now see clear guidance and a way to contact support instead.
Sep 17StudioShortened the sign-up survey by removing the question about working alone or with a team.
Sep 17StudioFixed Audio-to-MIDI's electronic drum-kit WAV exports failing whenever a transcription included a tom or crash cymbal.
Sep 17ModelsImproved video-to-music generation: the AI now analyzes your video directly to match timing and mood, instead of working from a text description of it.
Sep 17StudioFixed billing occasionally failing to load for accounts with a long transaction history.
Sep 16StudioMagic Mode's setup dialog no longer closes accidentally from a stray click outside it or the Escape key — use Skip, or the new Close button, instead. It also now fits and scrolls properly in shorter browser windows.
Sep 16StudioAudio-to-MIDI's MusicXML exports now use a consistent page layout, matching the PDF export, instead of leaving it up to whichever app opens them — fixing cases where the music started on page 2 instead of page 1.
Sep 16StudioSwitching to Score view, or between the full score and a single instrument, in Audio-to-MIDI is now noticeably faster, since Studio prepares recently viewed sheet music ahead of time.
Sep 16StudioAudio-to-MIDI's original recording now starts playing immediately when you switch to it, instead of waiting for the whole file to download and decode first.
Sep 16ModelsImproved Audio-to-MIDI's chord detection to follow the underlying musical structure more closely, so short passing notes and transcription noise no longer produce a busy, misleading chord chart.
Sep 16StudioYou can now listen to your uploaded audio directly from the instrument-review screen in Audio-to-MIDI, before generating results.
Sep 16StudioAudio-to-MIDI's WAV export now matches what you hear in the workbench — the same instruments and sound presets — and rendering long tracks no longer risks timing out.
Sep 16StudioFixed Audio-to-MIDI's sheet music showing a confusing "N.C." (no chord) label in spots where chord detection simply didn't have enough information — those spots are now left blank.
Sep 16StudioAudio-to-MIDI's MIDI and MusicXML download buttons now show a "Preparing…" indicator while the file is being generated, instead of appearing unresponsive.
Sep 16APITemporary file-access failures in the API are now retried automatically; if a request still fails, the response tells you when to retry.
Sep 15StudioFixed visible Audio-to-MIDI percussion notes sometimes being silent when the model could not identify the exact drum — unidentified hits now use a neutral click in playback, audition, audio renders, MIDI, and sheet music.
Sep 15APIThe Audio-to-MIDI API now limits each API key to five simultaneous background jobs by default, with higher limits available for high-volume integrations, and returns a clear retry signal if you go over it.
Sep 15ModelsFixed some Audio-to-MIDI transcriptions starting their first full bar slightly too early.
Sep 15StudioFixed Audio-to-MIDI file uploads occasionally failing right at the end if your sign-in session expired mid-upload — Studio now retries automatically instead of losing the file.
Sep 15APIImproved error handling when generating sound effects from video: clearly invalid videos now fail immediately with clear guidance instead of being retried, and error messages no longer expose raw internal service details.
Sep 12StudioFixed Audio-to-MIDI note results no longer streaming into the workbench as they were found, for both full transcriptions and retranscriptions — a recent fix had made every run wait until fully finished before showing anything.
Sep 12StudioFixed Audio-to-MIDI drum scores falling back to a simpler, less polished layout whenever a single hit couldn't be confidently identified — unidentified hits now get a neutral placeholder so the rest of the score still gets full engraving.
Sep 11PluginsThe Premiere, DaVinci Resolve, and REAPER plugins now read their generation limits (like sound length and extension length) live from the server at sign-in, so a server-side limit change takes effect immediately instead of waiting for a plugin update.
Sep 11PluginsFixed the DaVinci Resolve plugin's Copy and Cancel buttons on the connect screen being nearly invisible against the dark panel.
Sep 10StudioFixed the Audio-to-MIDI metronome's click sound occasionally failing to load due to an unrelated authentication check.
Sep 10StudioFixed server-side thumbnail generation failing outright for longer video projects — thumbnails for long videos now generate progressively instead of timing out.
Sep 10StudioThe loading indicator on a pending audio clip now sits at the center of the clip instead of the bottom-right corner.
Sep 10WebsiteFixed the Enterprise plan disappearing from the pricing page, and removed a duplicate Enterprise banner.
Sep 10StudioFixed Magic Mode preview playback being out of sync for sounds trimmed at their edges, where the wrong part of the audio played at the wrong point in the video.
Sep 10StudioFixed Magic Mode's progress bar getting stuck around 90% during longer generations — it now keeps advancing smoothly until the job actually finishes.
Sep 10PluginsThe Premiere, DaVinci Resolve, and REAPER plugins now report generation results per sample instead of all-or-nothing — a batch that partially fails still delivers the samples that worked, and asking for a sixth generation while five are already running shows a clear "wait for one to finish" message.
Sep 9StudioEditor actions like saving, generating, and uploading now start noticeably faster.
Sep 8APIThe Mirelo MCP server can now convert an audio recording into MIDI, MusicXML, and sheet music for connected AI assistants — ask it to transcribe a recording and get back note data or downloadable files.
Sep 7StudioFixed sheet music preparation occasionally showing a "transcription changed, please retry" message while a score was still finishing its initial processing — it now retries automatically instead.
Sep 7StudioFixed signed-in accounts occasionally getting stuck on an infinite loading screen with no way to sign out — Studio now offers a retry or sign-out option after a short wait.
Sep 7StudioFurther reduced Audio-to-MIDI sheet music falling back to a simpler layout, by automatically retrying after a rare rendering hiccup instead of giving up immediately.
Sep 7APIFixed some developer API accounts with a long usage history occasionally getting a temporary error on generation requests instead of the request going through.
Sep 6StudioFixed some subscribers upgrading from the Free plan receiving fewer included credits than their new plan advertises.
Sep 6StudioAudio-to-MIDI can now deliver print-ready, engraved PDF sheet music alongside MIDI, MusicXML, and audio — download the full score, an individual instrument part, or tablature, or grab everything at once as a ZIP.
Sep 6StudioRefined Studio's dark theme with a tighter, more polished neutral color palette, and fixed low-contrast destructive menu actions and inconsistent menu and dialog backgrounds.
Sep 5StudioFixed Studio getting stuck when it couldn't load an updated script after a deploy — it now reloads automatically once instead of repeating the same failure.
Sep 4StudioStudio no longer reloads when you switch pages after a routine deploy. The tab you already have open keeps working; a new tab or a refresh picks up the latest version.
Sep 4StudioFixed Audio-to-MIDI's sheet music view getting stuck retrying once you'd used up your daily AI analysis limit — score rendering now has its own separate allowance.
Sep 4StudioFixed some Audio-to-MIDI transcriptions silently falling back to a simpler, less polished score instead of the fully engraved sheet music.
Sep 4StudioAudio-to-MIDI drum transcriptions now correctly name and notate kick, snare, tom, hi-hat, and crash — some hits were previously mislabeled with the wrong percussion instrument.
Sep 4APIAudio-to-MIDI API requests can now opt into a higher-quality notation mode — with improved staff assignment, voicing, beaming, and spacing — at the cost of slightly slower processing.

August 2026

88 changes

Aug 28StudioFixed several dark mode contrast problems that made text hard to read — in the sign-in and sign-up forms, export dialog and playback controls, the timeline clip menu, and the Audio-to-MIDI review page.
Aug 28StudioAudio-to-MIDI playback now lets you pick between built-in sound presets for each instrument — like acoustic vs. electronic drums, or different guitar, bass, and piano tones — with a smart starting suggestion based on what was detected.
Aug 28StudioAudio-to-MIDI's instrument detection now retries automatically after a brief network or service hiccup, and lets you pick instruments by hand with a clear message if it still can't complete, instead of showing a generic failure.
Aug 28StudioAudio-to-MIDI's per-file length limit is now 15 minutes, up from 10 — the same increase applies to the API — with clearer guidance if a very long, high-quality file is still too large once decoded.
Aug 28StudioFixed the Audio-to-MIDI score view stuttering while a transcription was still streaming in new notes.
Aug 28StudioAudio-to-MIDI's per-instrument activity charts now scale independently, so quieter instruments are no longer flattened by a busier one in the same transcription.
Aug 28StudioHovering or dragging a track's volume fader in the timeline sidebar now shows the exact volume in decibels, matching the readout already available on clip volume lines.
Aug 28StudioFixed the Audio-to-MIDI score view's "Try again" button being unable to recover after a rendering error — it now actually retries instead of failing again immediately.
Aug 28StudioMagic Mode now adds multiple generated sounds to the timeline noticeably faster.
Aug 28APIThe sound-effect generation API now accepts much shorter minimum durations — 100 ms for plain text-to-sound-effect requests, 1 second for looped generation and audio extension — separate from Studio's higher editing minimums.
Aug 28StudioFixed a rare issue where a new sign-up could end up without an active plan if account setup hit an outdated billing record.
Aug 27StudioFixed some larger Audio-to-MIDI uploads and API requests failing unexpectedly, even when they were within the advertised size limit.
Aug 27StudioFixed dense Audio-to-MIDI transcriptions occasionally failing to save once processing had finished.
Aug 27StudioFixed the clip editor panel opening partly off-screen for clips lower in the timeline, which could make its buttons and fields unusable.
Aug 27StudioThe project editor now shows a clear "browser not supported" message on mobile Safari and on desktop Safari below version 26, instead of behaving unpredictably; Audio-to-MIDI and the rest of Studio remain available.
Aug 27StudioFixed timeline playback sometimes staying silent after previewing a single clip from the clip editor and closing it.
Aug 27StudioFixed creating a project from video files that use less common video codecs occasionally failing to keep a separate, editable soundtrack.
Aug 27APIThe developer API's new v3 endpoints simplify sound-effect generation into a single create/poll pattern, with clearer rate-limit headers, idempotency support, and a models catalogue — starting with text-to-sound-effects, asset uploads, and account info.
Aug 26StudioSimplified Audio-to-MIDI's upload flow: instrument detection now runs automatically in the background and reviewing its guesses is optional, so you can start a transcription right away instead of stepping through separate Upload, Review, and Generate screens.
Aug 26StudioFixed the editor's Play button sometimes doing nothing after leaving a project and coming back, which used to take several clicks to recover from.
Aug 25StudioAudio-to-MIDI now shows a clear "try again, or re-export as WAV or MP3" message when a file can't be decoded during transcription, instead of a generic internal-error notice.
Aug 25StudioFixed Audio-to-MIDI occasionally showing one transcription's notes on top of a different one after going back to the list and opening another.
Aug 25StudioFixed picking a file for Audio-to-MIDI sometimes failing silently with no way to recover if it became unavailable while you were still confirming the upload — it now shows a clear message asking you to pick the file again.
Aug 24StudioFixed Audio-to-MIDI's exported MusicXML and MIDI files showing dozens of spurious tempo changes for music played at a steady pace, instead of one accurate tempo.
Aug 24StudioAudio-to-MIDI's exported sheet music now notates guitar, bass, voice, and drum parts the way musicians actually read them — correct clefs, octave transposition for guitar and bass, and proper percussion notation for drums — instead of writing every note exactly where it sounds.
Aug 21StudioAudio-to-MIDI's generated vertical video can now be shared directly to Instagram or TikTok from your phone's share sheet, or downloaded on desktop to upload separately.
Aug 21StudioFixed a collapsed track group's summary bars overlapping the pinned video thumbnails in the timeline instead of scrolling underneath them.
Aug 21StudioAudio-to-MIDI's score view now renders sheet music in the background, so opening a large transcription no longer freezes the rest of Studio.
Aug 21APIThe Audio-to-MIDI API can now lock output to one fixed tempo — either the detected speed or a value you supply — and combine it with quantized timing.
Aug 20StudioAudio-to-MIDI's edit mode now lets you click or drag a note to preview its pitch and see its note name, without starting playback.
Aug 20StudioSwitching between pages in Studio (Projects, Extender, Ambiencer, Audio-to-MIDI, Settings, and more) now shows the page layout immediately instead of a blank screen while it loads.
Aug 19StudioAudio-to-MIDI now clearly labels its track list as "MIDI instruments" so it's not mistaken for isolated audio stems.
Aug 19StudioFixed quantized Audio-to-MIDI exports dropping notes from fast drum rolls and flams, where multiple hits rounded to the same instant.
Aug 19APISigned-in Studio users can now find and set up the hosted MCP server from a new Developer section in the sidebar, instead of only through the public /mcp page.
Aug 18StudioFixed the feedback form sometimes failing to submit right after your connection reconnected — it now retries automatically.
Aug 18StudioChanging your subscription plan is now a dedicated action in Studio's billing settings, with a clear confirmation once the change has taken effect, instead of relying on a generic billing portal.
Aug 17StudioFixed the Audio-to-MIDI toolbar clipping when the Studio sidebar was open, by making it responsive to its own available width instead of the browser's.
Aug 17StudioStudio no longer interrupts you with a "new version available" banner during routine deploys — it now quietly loads the latest version the next time you navigate to a different page.
Aug 16StudioFixed MIDI exports putting most non-drum instruments on the same channel, which made them play back as a single instrument in some external players — each instrument now gets its own channel.
Aug 15StudioFixed profile edits failing silently when the last name field was left blank.
Aug 15APIFixed the API Playground displaying your full API key on the page — it now shows a masked key and only uses the real value when you copy a request. Also fixed a video's upload status sometimes showing as ready before the upload had actually finished.
Aug 15APIFixed video analysis failing in the multi-stem sound-effects API and DaVinci Resolve plugin's multi-stem workflow.
Aug 14StudioFixed some uploaded WAV files with an embedded metadata tag being mislabeled and failing to preview.
Aug 14StudioFixed a backend hiccup that could show an error screen to every signed-in Studio user at once; recoverable issues now degrade gracefully instead.
Aug 14StudioMagic Mode's video analysis now automatically retries brief service overloads instead of failing right away, and shows a clear "try again in a few minutes" message on the rare occasion one still reaches you.
Aug 14StudioFixed Magic Mode sometimes uploading your video twice, or deleting staged clips while analysis was still running.
Aug 14StudioFixed Audio-to-MIDI audio continuing to play in the background after navigating away from the workbench.
Aug 14StudioAudio-to-MIDI playback now has an audible metronome that follows the detected beat, with its own volume control and a subtle visual pulse.

Aug 14WebsiteAdded a /developers hub that brings together our API docs, MCP setup, plugins, and changelog in one place.
Aug 13StudioFixed one broken audio clip in a project's timeline breaking playback for the whole project, with no indication of which clip was at fault — also fixed a rare case during video upload that could create such a broken clip in the first place.
Aug 13StudioFixed a rare backend hiccup causing an in-progress Audio-to-MIDI transcription to fail outright instead of retrying, even though it was about to finish.
Aug 13StudioRe-transcribing an Audio-to-MIDI result now shows new notes appearing progressively as they're detected, and keeps your last good result recoverable if the new attempt fails, instead of leaving the workbench stuck.
Aug 13StudioFixed MIDI export sometimes staying disabled indefinitely due to a background check that could hang.
Aug 13StudioFixed Audio-to-MIDI playback being silent on iPhone because instrument sound files failed to load.
Aug 13StudioAudio-to-MIDI's score (sheet music) view now supports clicking or using arrow keys directly on the notation to move the playhead, instead of requiring you to switch back to the piano roll.
Aug 13APIFixed the video-to-SFX API returning an error when given a slow-loading video URL, instead of proceeding with the request.
Aug 12StudioUploading a large video to create a project is now resumable — if the connection drops partway through, the upload continues from where it left off instead of restarting from the first byte.
Aug 12StudioTimeline clips can now be trimmed with the keyboard, not just the mouse — arrow keys move an edge by small steps, and Shift+arrow moves it by larger ones.
Aug 12StudioFixed exporting the audio render of a long Audio-to-MIDI transcription freezing the browser tab with no feedback — it now works in the background with progress shown, and a failed export explains what happened instead of failing silently.
Aug 12APISound effects generated by the experimental preserve-speech API now automatically duck under dialogue and mix at more consistent levels.
Aug 12APIThe experimental preserve-speech API endpoint's documentation is now visible to everyone, including signed-out visitors.
Aug 11StudioImproved accessibility for icon-only Studio buttons (play/pause, zoom, copy, delete, and similar) — screen readers now get a proper label instead of relying on a tooltip, and the timeline's Extend button always keeps a stable name instead of announcing its disabled-reason text.
Aug 11StudioFixed switching between generated ambience clips sometimes continuing to play the previous clip while the new one was still loading.

Aug 10StudioFixed a rare Audio-to-MIDI transcription failure caused by a note-timing mismatch in the transcription pipeline, with automatic recovery when possible.
Aug 10StudioMagic Mode's automatic whoosh sound effects are now genre-aware — documentary and interview-style footage no longer gets whoosh transitions meant for fast-cut, editorial-style videos.
Aug 10StudioFixed Audio-to-MIDI playback silently substituting the wrong instrument's sound when a sample failed to load — affected tracks now show a clear "No sound" warning instead, and recover automatically if a retry succeeds.
Aug 10StudioFixed Audio-to-MIDI sometimes showing a different tempo, meter, or key on screen than in the downloaded file for the same transcription.
Aug 10StudioFixed Audio-to-MIDI uploads on slow connections being cancelled by an overly strict time limit, and fixed a brief network hiccup during upload turning into a permanent failure instead of a retry.
Aug 10PluginsRoblox Studio plugin: fixed clicking Listen on a fresh sound sometimes saying it wasn't playable until you pressed Keep first.
Aug 7StudioThe Audio-to-MIDI page's empty state now leads with a clear "Drop your song here" upload prompt instead of descriptive text, and accepts a dropped file anywhere on the page.
Aug 6StudioFixed choppy, stuttering playback in the Audio-to-MIDI score view on dense transcriptions, and made the Follow Playhead option actually keep the view scrolled to the playhead.
Aug 6APIThe Audio-to-MIDI API now accepts an optional list of the instruments in your recording to improve transcription accuracy, matching the picker already available in Studio.
Aug 5StudioAudio-to-MIDI now accepts a much wider range of audio formats for upload — including FLAC, OGG, AIFF, M4A, and WebM — instead of only WAV and MP3.
Aug 5StudioFixed a rare timing issue for first-time Google sign-ups where the app could show an error immediately after registration instead of loading normally.
Aug 5StudioFixed Audio-to-MIDI sometimes exporting the wrong time signature for music in 3/4 or other non-4/4 meters when the beat detector wasn't fully confident, instead of defaulting to 4/4.
Aug 5APISound generation API endpoints (text-to-SFX, video-to-SFX, extend, and inpaint) now accept an optional seed for reproducible results.
Aug 5APISound generation API endpoints now let you choose the output audio format — WAV, MP3, AAC, or FLAC — instead of always returning WAV.
Aug 5StudioFixed Audio-to-MIDI MusicXML exports occasionally splitting a held note into several shorter, re-articulated notes when it clashed with another note in the same chord.
Aug 5StudioAudio-to-MIDI's key detection now declines to guess a key signature for chromatic or ambiguous music instead of assigning a misleading one.
Aug 4PluginsRoblox Studio plugin: if your account isn't connected to Roblox, or a sound gets blocked by Roblox's own moderation, you can now download the generated audio directly via a link instead of losing it.
Aug 4StudioAudio-to-MIDI now shows a clear message when an uploaded file can't be read as audio, with guidance to try re-exporting it, instead of a confusing decoder error or a "try again" that could never succeed.
Aug 4StudioFixed the sign-in and sign-up card border extending below the form with an empty gap on shorter screens.
Aug 4StudioExtending a sound in the timeline or standalone Extender tool can now generate up to 57 seconds of new audio, up from 30 — the same increase applies to the API and the Premiere, DaVinci, and REAPER plugins.
Aug 3StudioAudio-to-MIDI's instrument hints step no longer pre-selects the detector's guesses — you choose which instruments to include, with each suggestion's confidence score shown up front.
Aug 3StudioFixed pressing Space to play or pause in the Audio-to-MIDI workbench sometimes reopening the Export dialog instead, after closing it.
Aug 3APIThe Audio-to-MIDI API now supports the same choice Studio already offers: keep the original performance timing, or snap notes to the detected beat grid, with the response reporting which one was actually used.

Changelog

New features, models, plugins, and improvements across Mirelo Studio.

October 2026

29 changes

Oct 12StudioFixed Audio-to-MIDI sometimes playing an extra click sound alongside a recognized drum hit when the model wrote the same hit twice.
Oct 9StudioFree and Starter plans can now buy extra credits (top-ups) directly, the same way paid plans already could.
Oct 9StudioFixed a clip's typed description sometimes not being saved yet when you immediately clicked Generate, so Generate could use an old or empty description.
Oct 8StudioStarting an Audio-to-MIDI upload now retries automatically if your connection drops or stalls, instead of failing outright.
Oct 8StudioRemoved the Ambiencer tool from Studio.
Oct 8APIFixed rare API requests failing with a generic error during brief backend routing hiccups — they now retry automatically or return a clear "try again shortly" response.
Oct 8APIRedesigned the API Playground: a cleaner layout with a request/response side panel, friendlier model names, a history of past generations you can revisit, and background video uploads so you can start your next run without waiting.
Oct 7StudioFixed the clip editor's version-picker popup sometimes appearing hidden behind the video, timeline, or sidebars.
Oct 7StudioThe Editor Assistant now shows you the sounds it's about to generate, with cost estimates, so you can pick which ones to make before anything is charged.
Oct 7StudioAudio-to-MIDI can now record directly from your microphone or capture your computer's own audio (like a song playing in another tab), with trimming before you submit.
Oct 7APISped up the developer API: every response returns about 0.6 seconds faster, v3 jobs report as finished about 2 seconds sooner, and video uploads begin processing roughly a second faster.
Oct 6StudioScore and sheet-music downloads that stalled partway through now retry automatically, with a manual retry option if that doesn't fix it.
Oct 6StudioFixed video thumbnails failing to generate for clips with legitimately black frames.
Oct 5StudioFixed new accounts created while connecting Mirelo to an AI assistant losing the link back to finish that connection — you were dropped onto the Studio home page with the assistant left unconnected.
Oct 5StudioFixed a generated clip sometimes restarting from the beginning or playing silently after you paused and pressed play again.
Oct 5APIFixed a batch of developer API bugs found during a production review: video and audio inputs are now validated and rejected with a clear reason before a job starts, not after; unsupported request methods and invalid or blocked videos get accurate error messages; response headers report correct concurrency and rate-limit numbers; a prompt-length check no longer wrongly rejects prompts containing emoji; a gap where a blank duplicate-request key silently skipped duplicate-request protection is closed; and video requests that ran past the end of a clip are no longer billed for more audio than they actually received.
Oct 5StudioFixed some short generations being charged one extra credit due to a floating-point rounding error.
Oct 3APIThe API Playground's video-to-SFX page now plays back your uploaded video with a toggle to switch between the original and generated sound, so you can compare them in context.
Oct 3APIFixed the API Playground's video comparison player sometimes freezing on one frame while comparing your original and generated audio — playback now waits for buffering instead of repeatedly jumping.
Oct 2StudioAudio-to-MIDI now recovers automatically from more transient network hiccups when starting or checking on a transcription job.
Oct 2APISound effects generated through the developer API now have a 7-day retention period, with deletion taking up to 14 days. API jobs and results are available for 24 hours, and download links can expire sooner — save your results as soon as they finish.
Oct 2PluginsDaVinci Resolve plugin 1.6.0 fixes stem generation: stems no longer freeze Resolve or get lost after being paid for, they land trimmed and faded at the correct volume instead of raw (previously sometimes about 18 dB too loud), and they're grouped onto a few named tracks instead of one new track per sound.
Oct 2PluginsDaVinci Resolve plugin 1.6.0 also fixes generating sound from a timeline range leaving your export settings and timeline markers changed afterward, and fixes the Extend/Inpaint tabs showing no clips when the timeline contained certain non-media audio items.
Oct 2WebsiteRedesigned Mirelo's public website for phones — tighter spacing, readable screenshots, a full-screen menu instead of nested accordions, a fixed Terms page that no longer scrolls sideways, and a notice that the editor currently needs a desktop browser.
Oct 1StudioFixed Studio showing a blank white screen while signing in — it now shows the app shell immediately and offers a retry or sign-out option if authentication takes too long.
Oct 1StudioFixed Audio-to-MIDI transcriptions occasionally being marked as failed during a brief backend hiccup, even though the job was still running and would have finished normally.
Oct 1APIFixed the Audio-to-MIDI API occasionally losing a finished synchronous result (and returning an error) when a brief backend hiccup happened right as the job completed — it now retries so you still get your result.
Oct 1APIFixed the v3 API not honoring a per-key concurrency-limit increase, which could cause rate-limit errors even after we raised a customer's limit.
Oct 1WebsiteAdded a Creator Partnership page (mirelo.ai/creators) for paid collaboration applications.

124 changes

Sep 30StudioFixed clicking the timeline playhead (without dragging) jumping playback to the wrong time and stopping it.
Sep 30StudioFixed the editor sometimes playing silently, with no sound and no error, in Safari when another app was using your speakers — it now shows a notice and a way to recover.
Sep 30StudioUnified search, filters, and pagination across Studio's list pages, fixing three lists that previously stopped showing results after a fixed number of rows.
Sep 30StudioRemoved Studio's unused "project expires, restore by upgrading" messaging (the feature was never active) and clarified what deleting or removing a file actually does.
Sep 30APIThe API reference now opens on an overview page instead of dropping straight into one endpoint, and keeps the sidebar visible with working browser back and forward while you navigate.
Sep 29StudioFixed creating a video project from an audio-only file failing with a generic server error — Studio now catches this upfront and points you to Audio-to-MIDI.
Sep 29StudioFixed renaming an Audio-to-MIDI transcription with a long filename sometimes silently reverting to the old name.
Sep 29StudioFixed Audio-to-MIDI's metronome staying silent on iPhone due to an audio-timing error.
Sep 29APIThe Audio-to-MIDI API now offers a standalone instrument-detection endpoint, so integrations can get the same AI instrument suggestions Studio shows — detection is free when followed by a transcription.
Sep 29StudioFixed sign-up rarely completing when opened inside Instagram's or Facebook's built-in browser — email sign-up now comes first, since Google sign-in doesn't work in those browsers.
Sep 29StudioAudio-to-MIDI now detects copy-protected audio files at upload and explains why they can't be transcribed, instead of failing partway through with confusing errors.
Sep 29StudioMagic Mode's sound effects now default to a single combined track for new sessions instead of separated stems — you can still switch.
Sep 29StudioFixed the editor freezing or reloading itself after uploading a high-resolution video, caused by decoding too many timeline preview frames at once.
Sep 29StudioImproved keyboard accessibility across Studio (icon buttons, timeline drags, waveform handles) and stopped Gibberize from autoplaying its result with sound.
Sep 29StudioRedesigned the Profile and API keys settings pages for phones, with compact rows and an always-visible menu instead of a squeezed-down desktop layout.
Sep 29StudioFixed Google sign-in on Studio silently failing or looking stuck instead of showing an error you can retry from.
Sep 29StudioFixed video exports in Safari sometimes getting stuck indefinitely (often around 75%) with no file and no error message.

Sep 28StudioFixed sheet-music PDF preparation failing outright for songs whose triplets crossed a bar line after an irregular pickup measure.
Sep 28StudioFixed Studio's sign-in page staying blank with no message when required scripts failed to load — it now shows a clear error with a reload option and guidance.
Sep 28StudioFixed the Extender rejecting valid MP4, MOV, and some OGG files with an "Audio format not recognized" error.
Sep 28StudioFixed Audio-to-MIDI's instrument review getting stuck on "Audio preview unavailable" when a Windows computer's audio output failed — it now suggests checking your speakers and offers a retry.
Sep 28StudioFixed the editor saying an upload had failed while it was actually still in progress, which could lead you to delete a project that was uploading fine.
Sep 28StudioFixed Audio-to-MIDI's job list failing to load for accounts with many transcriptions, and not being searchable past the 100 most recent jobs.
Sep 28StudioFixed Audio-to-MIDI transcriptions occasionally failing outright due to an unrelated background scheduling hiccup right before the job started.
Sep 28APIThe v1 API now processes long videos in 60-second pieces for the 1.6 model (matching Studio and v2), instead of always using 10-second pieces, for fewer blended seams.
Sep 28ModelsFixed some Audio-to-MIDI drum transcriptions exporting hi-hat and tom hits as side-stick clicks in MIDI, sheet music, and playback, due to an outdated drum-mapping table for the current model.
Sep 28WebsiteFixed some marketing pages showing an error screen when background video autoplay was blocked by the browser.
Sep 26APIRestored the "Try it in the Playground" banner on each v3 API docs endpoint page.
Sep 25ModelsVoice transcriptions in Audio-to-MIDI can now play as a choir, a natural solo singer, or an electronic voice, with the AI suggesting a character from the source audio that you can change anytime, with loudness matched across all three options.
Sep 25PluginsFixed the plugins' and API's separated sound-effect stems losing very short sounds (like punches or clicks) on fast-cut footage — they're now preserved the way the web app already handles them.
Sep 25StudioAudio-to-MIDI can now transcribe lyrics for vocal tracks as a paid add-on — timed lyrics follow playback word by word and link to the notes being sung.
Sep 25StudioAudio-to-MIDI's lyrics now split Japanese, Chinese, and Korean words one character per note to match how those scores are written, instead of crowding a whole word under a single note.
Sep 25StudioLarge Audio-to-MIDI file uploads are now resumable — a dropped connection only re-sends the missing pieces instead of restarting the whole file from scratch.
Sep 25StudioFixed Studio crashing with a "Something went wrong" error for users with their browser's translate feature on, which mostly affected sign-up, sign-in, and Audio-to-MIDI for non-English speakers on iPhone.
Sep 25APIFixed video-to-SFX returning a generic server error for corrupt or undecodable video files — you'll now get a clear file-can't-be-processed message instead of repeated silent retries.
Sep 25StudioFixed Audio-to-MIDI's instrument-review screen showing "Audio preview unavailable" for AIFF files (which most browsers can't play) and some MP3s on Android — it now serves a browser-friendly preview copy.
Sep 25StudioFixed Audio-to-MIDI's Score view getting permanently stuck on "Couldn't render the score" after one failed attempt — opening Score now retries automatically, and a "Try again" button rebuilds without losing your edits.
Sep 25APIFixed the API's optimized MusicXML export falling back to the plain score for long pieces whose re-engraved file exceeded an overly conservative size limit.
Sep 25StudioFixed credit history mislabeling video-to-SFX generations as "Text to SFX" — it now shows "Video to SFX" to match what you actually used.
Sep 24APIThe v3 API reference is now shown to every visitor at /api-docs, including signed-out visitors and search engines, instead of only signed-in users.
Sep 24StudioFixed Audio-to-MIDI showing a misleading "stalled without detecting any notes" error when a transcription stalled after already finding notes.
Sep 24StudioFixed Audio-to-MIDI transcriptions failing immediately on an occasional transient "502 Bad Gateway" when starting — Studio now retries automatically.
Sep 24StudioFixed Audio-to-MIDI's original-audio playback showing "Original audio unavailable. Playing MIDI only." for about 5% of job opens, caused by a streaming link expiring before it was used.
Sep 24APIFixed the hosted MCP server rejecting agent platforms that can't do interactive sign-in — it now also accepts a Mirelo API key.
Sep 24WebsiteFixed Gibberize showing a generic error instead of clear guidance when a social video link was private, unavailable, or not a video.
Sep 23StudioFixed the Audio-to-MIDI metronome being silent in Chrome on Linux due to an incompatible click-sound format.
Sep 23APIThe developer API's video-to-SFX endpoint can now use the audio already inside your video to preserve existing dialogue, without needing you to extract and upload it as a separate file.
Sep 23StudioCustomers with personally billed Creator, Studio, Scale, or Business plans in EUR can now buy extra credits from the billing page, including during a trial.
Sep 23StudioAudio-to-MIDI's instrument picker is now a stable, searchable multi-select — choose several instruments without the menu closing or jumping after each pick.
Sep 23StudioFixed Audio-to-MIDI's Input–MIDI mix slider behaving incorrectly when the original recording failed to load — playback now switches cleanly to full MIDI instead.
Sep 23StudioFixed Studio suggesting you enable pay-per-use overage when running low on credits even if your account can't access that option — you'll now see relevant choices like buying credits or upgrading instead.
Sep 22StudioFixed Audio-to-MIDI's Score view failing to open on some lower-memory devices.
Sep 22StudioFixed Audio-to-MIDI's freshly uploaded audio preview sometimes disappearing if a background copy of the file failed to load.
Sep 22StudioFixed Audio-to-MIDI's Score view sometimes failing silently in Safari with no way to recover — it now retries automatically.
Sep 22ModelsAudio-to-MIDI now preserves triplets and swing rhythms in scores and exports instead of flattening them to straight notes, and you can select compound time signatures (6/8, 9/8, 12/8) when the music calls for it.
Sep 22PluginsThe Premiere, DaVinci Resolve, and REAPER plugins now show the same clear recovery guidance — enable overage, raise your limit, view plans, or contact support — when a generation can't be funded, instead of a disabled button or a dead-end error.
Sep 22StudioAudio-to-MIDI's instrument-detection step is noticeably faster.
Sep 21StudioFixed Command/Ctrl+A text selection in Studio input fields being invisible — it now shows the browser's native selection highlight.
Sep 21APISFX and Audio-to-MIDI API results now report which model release produced them, so you can tell exactly which model version generated a given output.
Sep 21StudioThe timeline's filmstrip now detects scene cuts and restarts at each one, so clicking a scene jumps the playhead straight to its start.
Sep 21ModelsAudio-to-MIDI now offers a realistic acoustic drum kit (the new default), accurately named electronic kits, and sound presets for instruments that previously had none — soloing a part in Score view also now produces a true single-part score.
Sep 18StudioFixed several Audio-to-MIDI playback bugs: Score's playhead no longer stalls, jumps backward, or lands on the wrong row when clicked; Restart now works immediately during playback; and selecting a later position no longer resets if the recording briefly buffers.
Sep 18StudioFixed some WAV files with unusual channel layouts failing to process for Audio-to-MIDI's instrument detection and audio preview.
Sep 18APIPublished a new API guide covering commercial use, attribution, and current operational limits for building products with Audio-to-MIDI and sound effects.
Sep 18StudioFixed dragging a new song onto an existing Audio-to-MIDI transcription skipping the upload consent and instrument-review steps.
Sep 18ModelsFixed Audio-to-MIDI sometimes adding an unnecessary empty pickup measure at the start of a score when a recording simply began with silence.
Sep 18StudioFixed an Audio-to-MIDI Pro output sometimes showing "Output not found" after deleting a different item from the list.
Sep 18StudioReplaced Audio-to-MIDI's fixed playback-mode picker with a single Input–MIDI mix slider that blends the original recording with generated MIDI in real time, and remembers your preferred balance.
Sep 18StudioFixed some Audio-to-MIDI performance-timed MIDI exports causing cut-off or missing notes in certain MIDI players.
Sep 18StudioAudio-to-MIDI now accepts recordings up to 30 minutes long, up from a shorter limit, in Studio and via the API.
Sep 18StudioAudio-to-MIDI now retries when sheet-music rendering is slow to start, giving the full score and PDF export another chance to load before falling back to simpler sheet music.
Sep 17StudioAudio-to-MIDI's export dialog now lets you choose exactly which instruments to include — any combination, not just the full mix or a single instrument — for MIDI, MusicXML, and audio exports, with everything selected by default.
Sep 17StudioAudio-to-MIDI's full scores and MIDI instrument sidebar now use the same, stable instrument order, so arrangements no longer get shuffled between transcriptions or between the two views.
Sep 17ModelsAudio-to-MIDI is now officially Audio-to-MIDI Pro — read what's new in our launch announcement and updated product page.
Sep 17StudioFixed Audio-to-MIDI's original-recording playback and stereo comparison failing to load on older versions of Chrome (109 and earlier).
Sep 17StudioFixed vocal (Lead and Aahs) instrument playback in Audio-to-MIDI being noticeably quieter than the rest of the arrangement.
Sep 17StudioFixed selected-range re-transcription in Audio-to-MIDI being unusable when started from Score view — it now switches to Piano Roll, where range selection lives, and stays there.
Sep 17StudioFixed Studio showing an unusable credit balance when credit provisioning was still catching up — affected accounts now see clear guidance and a way to contact support instead.
Sep 17StudioShortened the sign-up survey by removing the question about working alone or with a team.
Sep 17StudioFixed Audio-to-MIDI's electronic drum-kit WAV exports failing whenever a transcription included a tom or crash cymbal.
Sep 17ModelsImproved video-to-music generation: the AI now analyzes your video directly to match timing and mood, instead of working from a text description of it.
Sep 17StudioFixed billing occasionally failing to load for accounts with a long transaction history.
Sep 16StudioMagic Mode's setup dialog no longer closes accidentally from a stray click outside it or the Escape key — use Skip, or the new Close button, instead. It also now fits and scrolls properly in shorter browser windows.
Sep 16StudioAudio-to-MIDI's MusicXML exports now use a consistent page layout, matching the PDF export, instead of leaving it up to whichever app opens them — fixing cases where the music started on page 2 instead of page 1.
Sep 16StudioSwitching to Score view, or between the full score and a single instrument, in Audio-to-MIDI is now noticeably faster, since Studio prepares recently viewed sheet music ahead of time.
Sep 16StudioAudio-to-MIDI's original recording now starts playing immediately when you switch to it, instead of waiting for the whole file to download and decode first.
Sep 16ModelsImproved Audio-to-MIDI's chord detection to follow the underlying musical structure more closely, so short passing notes and transcription noise no longer produce a busy, misleading chord chart.
Sep 16StudioYou can now listen to your uploaded audio directly from the instrument-review screen in Audio-to-MIDI, before generating results.
Sep 16StudioAudio-to-MIDI's WAV export now matches what you hear in the workbench — the same instruments and sound presets — and rendering long tracks no longer risks timing out.
Sep 16StudioFixed Audio-to-MIDI's sheet music showing a confusing "N.C." (no chord) label in spots where chord detection simply didn't have enough information — those spots are now left blank.
Sep 16StudioAudio-to-MIDI's MIDI and MusicXML download buttons now show a "Preparing…" indicator while the file is being generated, instead of appearing unresponsive.
Sep 16APITemporary file-access failures in the API are now retried automatically; if a request still fails, the response tells you when to retry.
Sep 15StudioFixed visible Audio-to-MIDI percussion notes sometimes being silent when the model could not identify the exact drum — unidentified hits now use a neutral click in playback, audition, audio renders, MIDI, and sheet music.
Sep 15APIThe Audio-to-MIDI API now limits each API key to five simultaneous background jobs by default, with higher limits available for high-volume integrations, and returns a clear retry signal if you go over it.
Sep 15ModelsFixed some Audio-to-MIDI transcriptions starting their first full bar slightly too early.
Sep 15StudioFixed Audio-to-MIDI file uploads occasionally failing right at the end if your sign-in session expired mid-upload — Studio now retries automatically instead of losing the file.
Sep 15APIImproved error handling when generating sound effects from video: clearly invalid videos now fail immediately with clear guidance instead of being retried, and error messages no longer expose raw internal service details.
Sep 12StudioFixed Audio-to-MIDI note results no longer streaming into the workbench as they were found, for both full transcriptions and retranscriptions — a recent fix had made every run wait until fully finished before showing anything.
Sep 12StudioFixed Audio-to-MIDI drum scores falling back to a simpler, less polished layout whenever a single hit couldn't be confidently identified — unidentified hits now get a neutral placeholder so the rest of the score still gets full engraving.
Sep 11PluginsThe Premiere, DaVinci Resolve, and REAPER plugins now read their generation limits (like sound length and extension length) live from the server at sign-in, so a server-side limit change takes effect immediately instead of waiting for a plugin update.
Sep 11PluginsFixed the DaVinci Resolve plugin's Copy and Cancel buttons on the connect screen being nearly invisible against the dark panel.
Sep 10StudioFixed the Audio-to-MIDI metronome's click sound occasionally failing to load due to an unrelated authentication check.
Sep 10StudioFixed server-side thumbnail generation failing outright for longer video projects — thumbnails for long videos now generate progressively instead of timing out.
Sep 10StudioThe loading indicator on a pending audio clip now sits at the center of the clip instead of the bottom-right corner.
Sep 10WebsiteFixed the Enterprise plan disappearing from the pricing page, and removed a duplicate Enterprise banner.
Sep 10StudioFixed Magic Mode preview playback being out of sync for sounds trimmed at their edges, where the wrong part of the audio played at the wrong point in the video.
Sep 10StudioFixed Magic Mode's progress bar getting stuck around 90% during longer generations — it now keeps advancing smoothly until the job actually finishes.
Sep 10PluginsThe Premiere, DaVinci Resolve, and REAPER plugins now report generation results per sample instead of all-or-nothing — a batch that partially fails still delivers the samples that worked, and asking for a sixth generation while five are already running shows a clear "wait for one to finish" message.
Sep 9StudioEditor actions like saving, generating, and uploading now start noticeably faster.
Sep 8APIThe Mirelo MCP server can now convert an audio recording into MIDI, MusicXML, and sheet music for connected AI assistants — ask it to transcribe a recording and get back note data or downloadable files.
Sep 7StudioFixed sheet music preparation occasionally showing a "transcription changed, please retry" message while a score was still finishing its initial processing — it now retries automatically instead.
Sep 7StudioFixed signed-in accounts occasionally getting stuck on an infinite loading screen with no way to sign out — Studio now offers a retry or sign-out option after a short wait.
Sep 7StudioFurther reduced Audio-to-MIDI sheet music falling back to a simpler layout, by automatically retrying after a rare rendering hiccup instead of giving up immediately.
Sep 7APIFixed some developer API accounts with a long usage history occasionally getting a temporary error on generation requests instead of the request going through.
Sep 6StudioFixed some subscribers upgrading from the Free plan receiving fewer included credits than their new plan advertises.
Sep 6StudioAudio-to-MIDI can now deliver print-ready, engraved PDF sheet music alongside MIDI, MusicXML, and audio — download the full score, an individual instrument part, or tablature, or grab everything at once as a ZIP.
Sep 6StudioRefined Studio's dark theme with a tighter, more polished neutral color palette, and fixed low-contrast destructive menu actions and inconsistent menu and dialog backgrounds.
Sep 5StudioFixed Studio getting stuck when it couldn't load an updated script after a deploy — it now reloads automatically once instead of repeating the same failure.
Sep 4StudioStudio no longer reloads when you switch pages after a routine deploy. The tab you already have open keeps working; a new tab or a refresh picks up the latest version.
Sep 4StudioFixed Audio-to-MIDI's sheet music view getting stuck retrying once you'd used up your daily AI analysis limit — score rendering now has its own separate allowance.
Sep 4StudioFixed some Audio-to-MIDI transcriptions silently falling back to a simpler, less polished score instead of the fully engraved sheet music.
Sep 4StudioAudio-to-MIDI drum transcriptions now correctly name and notate kick, snare, tom, hi-hat, and crash — some hits were previously mislabeled with the wrong percussion instrument.
Sep 4APIAudio-to-MIDI API requests can now opt into a higher-quality notation mode — with improved staff assignment, voicing, beaming, and spacing — at the cost of slightly slower processing.

August 2026

88 changes

Aug 28StudioFixed several dark mode contrast problems that made text hard to read — in the sign-in and sign-up forms, export dialog and playback controls, the timeline clip menu, and the Audio-to-MIDI review page.
Aug 28StudioAudio-to-MIDI playback now lets you pick between built-in sound presets for each instrument — like acoustic vs. electronic drums, or different guitar, bass, and piano tones — with a smart starting suggestion based on what was detected.
Aug 28StudioAudio-to-MIDI's instrument detection now retries automatically after a brief network or service hiccup, and lets you pick instruments by hand with a clear message if it still can't complete, instead of showing a generic failure.
Aug 28StudioAudio-to-MIDI's per-file length limit is now 15 minutes, up from 10 — the same increase applies to the API — with clearer guidance if a very long, high-quality file is still too large once decoded.
Aug 28StudioFixed the Audio-to-MIDI score view stuttering while a transcription was still streaming in new notes.
Aug 28StudioAudio-to-MIDI's per-instrument activity charts now scale independently, so quieter instruments are no longer flattened by a busier one in the same transcription.
Aug 28StudioHovering or dragging a track's volume fader in the timeline sidebar now shows the exact volume in decibels, matching the readout already available on clip volume lines.
Aug 28StudioFixed the Audio-to-MIDI score view's "Try again" button being unable to recover after a rendering error — it now actually retries instead of failing again immediately.
Aug 28StudioMagic Mode now adds multiple generated sounds to the timeline noticeably faster.
Aug 28APIThe sound-effect generation API now accepts much shorter minimum durations — 100 ms for plain text-to-sound-effect requests, 1 second for looped generation and audio extension — separate from Studio's higher editing minimums.
Aug 28StudioFixed a rare issue where a new sign-up could end up without an active plan if account setup hit an outdated billing record.
Aug 27StudioFixed some larger Audio-to-MIDI uploads and API requests failing unexpectedly, even when they were within the advertised size limit.

Aug 27StudioFixed the clip editor panel opening partly off-screen for clips lower in the timeline, which could make its buttons and fields unusable.
Aug 27StudioThe project editor now shows a clear "browser not supported" message on mobile Safari and on desktop Safari below version 26, instead of behaving unpredictably; Audio-to-MIDI and the rest of Studio remain available.
Aug 27StudioFixed timeline playback sometimes staying silent after previewing a single clip from the clip editor and closing it.
Aug 27StudioFixed creating a project from video files that use less common video codecs occasionally failing to keep a separate, editable soundtrack.
Aug 27APIThe developer API's new v3 endpoints simplify sound-effect generation into a single create/poll pattern, with clearer rate-limit headers, idempotency support, and a models catalogue — starting with text-to-sound-effects, asset uploads, and account info.
Aug 26StudioSimplified Audio-to-MIDI's upload flow: instrument detection now runs automatically in the background and reviewing its guesses is optional, so you can start a transcription right away instead of stepping through separate Upload, Review, and Generate screens.
Aug 26StudioFixed the editor's Play button sometimes doing nothing after leaving a project and coming back, which used to take several clicks to recover from.
Aug 25StudioAudio-to-MIDI now shows a clear "try again, or re-export as WAV or MP3" message when a file can't be decoded during transcription, instead of a generic internal-error notice.
Aug 25StudioFixed Audio-to-MIDI occasionally showing one transcription's notes on top of a different one after going back to the list and opening another.
Aug 25StudioFixed picking a file for Audio-to-MIDI sometimes failing silently with no way to recover if it became unavailable while you were still confirming the upload — it now shows a clear message asking you to pick the file again.
Aug 24StudioFixed Audio-to-MIDI's exported MusicXML and MIDI files showing dozens of spurious tempo changes for music played at a steady pace, instead of one accurate tempo.
Aug 24StudioAudio-to-MIDI's exported sheet music now notates guitar, bass, voice, and drum parts the way musicians actually read them — correct clefs, octave transposition for guitar and bass, and proper percussion notation for drums — instead of writing every note exactly where it sounds.
Aug 21StudioAudio-to-MIDI's generated vertical video can now be shared directly to Instagram or TikTok from your phone's share sheet, or downloaded on desktop to upload separately.
Aug 21StudioFixed a collapsed track group's summary bars overlapping the pinned video thumbnails in the timeline instead of scrolling underneath them.
Aug 21StudioAudio-to-MIDI's score view now renders sheet music in the background, so opening a large transcription no longer freezes the rest of Studio.
Aug 21APIThe Audio-to-MIDI API can now lock output to one fixed tempo — either the detected speed or a value you supply — and combine it with quantized timing.
Aug 20StudioAudio-to-MIDI's edit mode now lets you click or drag a note to preview its pitch and see its note name, without starting playback.
Aug 20StudioSwitching between pages in Studio (Projects, Extender, Ambiencer, Audio-to-MIDI, Settings, and more) now shows the page layout immediately instead of a blank screen while it loads.
Aug 19StudioAudio-to-MIDI now clearly labels its track list as "MIDI instruments" so it's not mistaken for isolated audio stems.
Aug 19StudioFixed quantized Audio-to-MIDI exports dropping notes from fast drum rolls and flams, where multiple hits rounded to the same instant.
Aug 19APISigned-in Studio users can now find and set up the hosted MCP server from a new Developer section in the sidebar, instead of only through the public /mcp page.
Aug 18StudioFixed the feedback form sometimes failing to submit right after your connection reconnected — it now retries automatically.
Aug 18StudioChanging your subscription plan is now a dedicated action in Studio's billing settings, with a clear confirmation once the change has taken effect, instead of relying on a generic billing portal.
Aug 17StudioFixed the Audio-to-MIDI toolbar clipping when the Studio sidebar was open, by making it responsive to its own available width instead of the browser's.
Aug 17StudioStudio no longer interrupts you with a "new version available" banner during routine deploys — it now quietly loads the latest version the next time you navigate to a different page.
Aug 16StudioFixed MIDI exports putting most non-drum instruments on the same channel, which made them play back as a single instrument in some external players — each instrument now gets its own channel.
Aug 15StudioFixed profile edits failing silently when the last name field was left blank.
Aug 15APIFixed the API Playground displaying your full API key on the page — it now shows a masked key and only uses the real value when you copy a request. Also fixed a video's upload status sometimes showing as ready before the upload had actually finished.
Aug 15APIFixed video analysis failing in the multi-stem sound-effects API and DaVinci Resolve plugin's multi-stem workflow.
Aug 14StudioFixed some uploaded WAV files with an embedded metadata tag being mislabeled and failing to preview.
Aug 14StudioFixed a backend hiccup that could show an error screen to every signed-in Studio user at once; recoverable issues now degrade gracefully instead.
Aug 14StudioMagic Mode's video analysis now automatically retries brief service overloads instead of failing right away, and shows a clear "try again in a few minutes" message on the rare occasion one still reaches you.
Aug 14StudioFixed Magic Mode sometimes uploading your video twice, or deleting staged clips while analysis was still running.
Aug 14StudioFixed Audio-to-MIDI audio continuing to play in the background after navigating away from the workbench.

Aug 14StudioFixed destructive confirmation dialogs (like delete) closing if you accidentally clicked outside them.
Aug 14WebsiteAdded a /developers hub that brings together our API docs, MCP setup, plugins, and changelog in one place.
Aug 13StudioFixed one broken audio clip in a project's timeline breaking playback for the whole project, with no indication of which clip was at fault — also fixed a rare case during video upload that could create such a broken clip in the first place.
Aug 13StudioFixed a rare backend hiccup causing an in-progress Audio-to-MIDI transcription to fail outright instead of retrying, even though it was about to finish.
Aug 13StudioRe-transcribing an Audio-to-MIDI result now shows new notes appearing progressively as they're detected, and keeps your last good result recoverable if the new attempt fails, instead of leaving the workbench stuck.
Aug 13StudioFixed MIDI export sometimes staying disabled indefinitely due to a background check that could hang.
Aug 13StudioFixed Audio-to-MIDI playback being silent on iPhone because instrument sound files failed to load.
Aug 13StudioAudio-to-MIDI's score (sheet music) view now supports clicking or using arrow keys directly on the notation to move the playhead, instead of requiring you to switch back to the piano roll.
Aug 13APIFixed the video-to-SFX API returning an error when given a slow-loading video URL, instead of proceeding with the request.
Aug 12StudioUploading a large video to create a project is now resumable — if the connection drops partway through, the upload continues from where it left off instead of restarting from the first byte.
Aug 12StudioTimeline clips can now be trimmed with the keyboard, not just the mouse — arrow keys move an edge by small steps, and Shift+arrow moves it by larger ones.
Aug 12StudioFixed exporting the audio render of a long Audio-to-MIDI transcription freezing the browser tab with no feedback — it now works in the background with progress shown, and a failed export explains what happened instead of failing silently.
Aug 12APISound effects generated by the experimental preserve-speech API now automatically duck under dialogue and mix at more consistent levels.
Aug 12APIThe experimental preserve-speech API endpoint's documentation is now visible to everyone, including signed-out visitors.
Aug 11StudioImproved accessibility for icon-only Studio buttons (play/pause, zoom, copy, delete, and similar) — screen readers now get a proper label instead of relying on a tooltip, and the timeline's Extend button always keeps a stable name instead of announcing its disabled-reason text.
Aug 11StudioFixed switching between generated ambience clips sometimes continuing to play the previous clip while the new one was still loading.
Aug 11PluginsEditor plugin connect links that expire after ten minutes used to show a button that looked active but failed silently — they now show a clear "Link Expired" message.
Aug 10StudioFixed a rare Audio-to-MIDI transcription failure caused by a note-timing mismatch in the transcription pipeline, with automatic recovery when possible.
Aug 10StudioMagic Mode's automatic whoosh sound effects are now genre-aware — documentary and interview-style footage no longer gets whoosh transitions meant for fast-cut, editorial-style videos.
