Mirelo

Changelog

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

August 2026

  • StudioFixed a rare Audio-to-MIDI transcription failure caused by a note-timing mismatch in the transcription pipeline, with automatic recovery when possible.
  • StudioThe 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.
  • StudioFixed 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.
  • APIThe 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.
  • StudioAudio-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.
  • StudioFixed a rare timing issue for first-time Google sign-ups where the app could show an error immediately after registration instead of loading normally.
  • StudioFixed 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.
  • APISound generation API endpoints (text-to-SFX, video-to-SFX, extend, and inpaint) now accept an optional seed for reproducible results.
  • APISound generation API endpoints now let you choose the output audio format — WAV, MP3, AAC, or FLAC — instead of always returning WAV.
  • StudioFixed 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.
  • StudioAudio-to-MIDI's key detection now declines to guess a key signature for chromatic or ambiguous music instead of assigning a misleading one.
  • PluginsRoblox 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.
  • StudioAudio-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.
  • StudioFixed the sign-in and sign-up card border extending below the form with an empty gap on shorter screens.
  • StudioExtending 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.
  • StudioAudio-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.
  • StudioFixed pressing Space to play or pause in the Audio-to-MIDI workbench sometimes reopening the Export dialog instead, after closing it.
  • APIThe 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.

July 2026

  • StudioFixed Studio sometimes showing an incorrect "not enough credits" error while a new credit grant was still being set up.
  • StudioFixed some video exports failing outright due to a timing issue in the source video, with audio kept in sync as part of the fix.
  • StudioDuplicating a locked, video-synced sound now creates a movable, unsynced copy instead of keeping the same lock, so you can reuse a good generation later in your video.
  • StudioAudio-to-MIDI's export dialog now lets you choose whether notes follow your actual performance timing or snap to one fixed tempo, with quantizing available as an independent option.
  • StudioFixed sustained notes and chords being cut short in MusicXML exports — notes and chords now keep the length they were actually played.
  • APIMirelo MCP is live — connect Claude, ChatGPT, Cursor, or another MCP-compatible assistant and generate sound effects from text or video, extend a clip, or replace part of one, without leaving the chat. Setup guides are at mirelo.ai/mcp.
  • WebsiteFixed the contact-sales form showing unreadable dark text on a dark background in light mode.
  • APIFixed API reference tables being cut off with no way to scroll on mobile.
  • WebsiteAdded a public Studio how-to guide at mirelo.ai/docs, covering upload, sound generation, export, and credits.
  • StudioFixed exported MIDI and MusicXML files losing sync with the music's actual bar lines — exports now follow the performance's real tempo and meter instead of a fixed guess.
  • APIThe API now returns more detail about your credit balance — period usage, plan allocation, and whether a new grant is still being set up.
  • APIFixed the Audio-to-MIDI API failing outright when it couldn't quickly fetch audio from certain source URLs.
  • APIAudio-to-MIDI API jobs now return partial transcribed notes while still processing, instead of only once the job fully completes.

  • StudioFixed the original audio track going silent after re-transcribing the same recording in Audio-to-MIDI.
  • StudioFixed the Audio-to-MIDI piano roll's note resize handles being too small to grab reliably — you can now consistently shorten, lengthen, or drag a note's start time.
  • StudioAudio-to-MIDI transcriptions of piano, electric piano, organ, and harp parts now export as a proper two-staff grand staff instead of a single hard-to-read staff.
  • WebsiteFixed the pricing page potentially hanging indefinitely if it couldn't quickly reach the backend — it now falls back to standard pricing within a few seconds.
  • StudioFixed a false "a new version of Studio is available" banner appearing immediately after every signup.
  • StudioClicking a collapsed sidebar item with sub-items, like API Playground, now automatically expands the sidebar so the sub-items are reachable.
  • StudioSignup now takes you straight into Studio on the Free plan instead of showing a blocking plan-selection screen first; you'll be asked about marketing emails later instead of during signup.
  • StudioRemoved a non-functional sparkles button that appeared on some timeline clips without doing anything useful.
  • StudioRedesigned the editor timeline with a cleaner white surface, taller clips, a quieter time ruler, and playback controls moved into the timeline header, with fixed scrolling over the track sidebar.
  • StudioReplaced the editor's Export dropdown with a dialog that clearly lists every export option (MP4, audio tracks, FCP7 XML, AAF).
  • PluginsDaVinci Resolve plugin: added an experimental Magic Mode-style multi-stem sound generation option, detecting distinct sound sources and placing one generated clip per source on its own track, with the ability to regenerate an individual stem.
  • StudioFixed the clip editor's Pick Versions tab showing an empty panel for clips that haven't generated anything yet — it now opens Create New instead.
  • ModelsRemoved the older SFX model version from the video- and text-to-sound generator and API docs/playground — new Studio generations now use the latest model only.
  • APIThe API Playground now shows the specific error a request failed with instead of a generic 400, and leaves optional parameters empty until you set them so it's clear what's actually required.
  • APIThe public API now supports Audio-to-MIDI, so you can transcribe audio into MIDI, structured notes, or MusicXML — synchronously or as a background job.
  • StudioFixed sound generation failing with an error when combining a text prompt with Model 1.5 in the video-based generator's Advanced options.
  • WebsiteGibberize now shows a Download button on desktop instead of a share sheet that only offered Copy and AirDrop.
  • WebsiteGibberize's free daily limit doubled from 5 to 10 generations.

  • StudioFixed audio-to-MIDI transcription hanging indefinitely on longer audio tracks.
  • StudioFailed sound generations now show a Try Again button, and brief server hiccups are retried automatically instead of failing the generation outright.
  • StudioFixed Google sign-in failing when Studio is opened inside apps like WhatsApp, Instagram, or Messenger — email sign-in now shows instead, with a copyable link to open in your regular browser.
  • WebsiteGibberize can now import a source video directly from a TikTok or Instagram link, in addition to recording or uploading.
  • StudioFixed the plan page showing some legacy Free accounts as already on the current plan instead of offering the option to switch.
  • StudioMagic Mode now stops cleanly and explains what happened when you don't have enough credits, instead of partially generating results and unexpectedly closing.
  • StudioNew projects are now named after your uploaded video's filename instead of always starting as "Untitled Project."
  • StudioFixed a bug where sound effects generated from video could lose sync with the video if dragged to a different track.
  • WebsiteLaunched Gibberize (mirelo.ai/gibberize) — a free tool that dubs any video into a gibberish voice-over you can share straight to TikTok or Instagram Reels, no account required. Also added to Studio's Tools for signed-in users.
  • StudioFixed an error when subscribers with a trialing or past-due plan tried to switch plans — they're now sent to the billing portal instead of seeing an error.
  • StudioReduced sound generation failures caused by brief hiccups downloading your video.
  • StudioFixed the Ambiencer loop tool allowing a duration below the minimum, which caused generation to fail.

  • APIThe video-to-SFX API now accepts an optional prompt to guide the generated sound while keeping timing synced to your video.
  • StudioMagic Mode's setup screen now floats over the editor as an overlay instead of replacing the timeline, with richer sound effect, music, and Foley option cards.
  • StudioStudio's sidebar can now collapse into a compact icon rail, and remembers your preference across sessions.
  • StudioHold Option (Alt on Windows) while dragging a timeline clip to duplicate it instead of moving it.
  • StudioFixed the video preview sometimes shrinking to an unusably small size in the editor, with no way to recover it by dragging the divider.

  • PluginsFixed the DaVinci Resolve plugin blocking sound generation with a false "offline media" error for clips that were actually available.
