- StudioFixed 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.
- StudioFixed some WAV files with unusual channel layouts failing to process for Audio-to-MIDI's instrument detection and audio preview.
- APIPublished a new API guide covering commercial use, attribution, and current operational limits for building products with Audio-to-MIDI and sound effects.
- StudioFixed dragging a new song onto an existing Audio-to-MIDI transcription skipping the upload consent and instrument-review steps.
- ModelsFixed Audio-to-MIDI sometimes adding an unnecessary empty pickup measure at the start of a score when a recording simply began with silence.
- StudioFixed an Audio-to-MIDI Pro output sometimes showing "Output not found" after deleting a different item from the list.
- StudioReplaced 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.
- StudioFixed some Audio-to-MIDI performance-timed MIDI exports causing cut-off or missing notes in certain MIDI players.
- StudioAudio-to-MIDI now accepts recordings up to 30 minutes long, up from a shorter limit, in Studio and via the API.
- StudioAudio-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.
- StudioAudio-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.
- StudioAudio-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.
- ModelsAudio-to-MIDI is now officially Audio-to-MIDI Pro — read what's new in our launch announcement and updated product page.
- StudioFixed Audio-to-MIDI's original-recording playback and stereo comparison failing to load on older versions of Chrome (109 and earlier).
- StudioFixed vocal (Lead and Aahs) instrument playback in Audio-to-MIDI being noticeably quieter than the rest of the arrangement.
- StudioFixed 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.
- StudioFixed 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.
- StudioShortened the sign-up survey by removing the question about working alone or with a team.
- StudioFixed Audio-to-MIDI's electronic drum-kit WAV exports failing whenever a transcription included a tom or crash cymbal.
- ModelsImproved 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.
- StudioFixed billing occasionally failing to load for accounts with a long transaction history.
- StudioMagic 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.
- StudioAudio-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.
- StudioSwitching 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.
- StudioAudio-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.
- ModelsImproved 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.
- StudioYou can now listen to your uploaded audio directly from the instrument-review screen in Audio-to-MIDI, before generating results.
- StudioAudio-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.
- StudioFixed 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.
- StudioAudio-to-MIDI's MIDI and MusicXML download buttons now show a "Preparing…" indicator while the file is being generated, instead of appearing unresponsive.
- APITemporary file-access failures in the API are now retried automatically; if a request still fails, the response tells you when to retry.
- StudioFixed 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.
- APIThe 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.
- ModelsFixed some Audio-to-MIDI transcriptions starting their first full bar slightly too early.
- StudioFixed 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.
- APIImproved 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.
- StudioFixed 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.
- StudioFixed 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.
- PluginsThe 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.
- PluginsFixed the DaVinci Resolve plugin's Copy and Cancel buttons on the connect screen being nearly invisible against the dark panel.
- StudioFixed the Audio-to-MIDI metronome's click sound occasionally failing to load due to an unrelated authentication check.
- StudioFixed server-side thumbnail generation failing outright for longer video projects — thumbnails for long videos now generate progressively instead of timing out.
- StudioThe loading indicator on a pending audio clip now sits at the center of the clip instead of the bottom-right corner.
- WebsiteFixed the Enterprise plan disappearing from the pricing page, and removed a duplicate Enterprise banner.
- StudioFixed 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.
- StudioFixed Magic Mode's progress bar getting stuck around 90% during longer generations — it now keeps advancing smoothly until the job actually finishes.
- PluginsThe 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.
- StudioEditor actions like saving, generating, and uploading now start noticeably faster.
- APIThe 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.
- StudioFixed 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.
- StudioFixed 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.
- StudioFurther 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.
- APIFixed some developer API accounts with a long usage history occasionally getting a temporary error on generation requests instead of the request going through.
- StudioFixed some subscribers upgrading from the Free plan receiving fewer included credits than their new plan advertises.
- StudioAudio-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.
- StudioRefined 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.
- StudioFixed 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.
- StudioStudio 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.
- StudioFixed 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.
- StudioFixed some Audio-to-MIDI transcriptions silently falling back to a simpler, less polished score instead of the fully engraved sheet music.
- StudioAudio-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.
- APIAudio-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.
