Sheet Music 1.2.0

Released July 13, 2026

New Features and Improvements

• Requires Ableton Live Suite 12.4.5b5 or newer: Live 12.4.5b5 fixed the temporary-folder permission bug (Ableton bug L12-BUG-5145) that could stop the chart window from opening on the first Live launch after restarting your Mac. This release removes the workaround and raises the minimum supported Live version. Verified on Live 12.4.5b6 and 12.4.5b7. (#5)
• Notation engine update: OpenSheetMusicDisplay 2.0 renders faster and makes re-renders (changing clef, grid, or time signature in the chart window) identical to the first render.
• Refreshed internals: the project moved from npm to pnpm and all dependencies were updated (TypeScript 7, Vite 8, Vitest 4, jsPDF 4).

v1.1.0

Released June 9, 2026

New Features and Improvements

• Added an info/credits panel, opened by a new ⓘ button in the toolbar, that shows the bundled open-source license notices (OpenSheetMusicDisplay and its dependencies) so the distribution complies with their license terms.

Bugfixes

• Fixed a temp-directory permission race in the Extension Host that could prevent the chart window from opening on the first launch after a reboot.

Changes

• Refreshed the social preview card and streamlined the README.

v1.0.0 — Sheet Music for Ableton Live

Released June 4, 2026

View any MIDI clip in Ableton Live as readable sheet music, transpose it for any instrument, and export MusicXML, PDF, or PNG.

New Features and Improvements

• Added Show Chart to the right-click menu of any MIDI clip, rendering the clip as notation with OpenSheetMusicDisplay.
• Added transposition by instrument preset (Concert/C, Eb Alto Sax, Bb Trumpet/Clarinet, Bb Tenor Sax, Eb Baritone Sax, F Horn) or by an arbitrary number of semitones. The key signature follows the transposition automatically.
• Added automatic clef detection for treble, bass, or a two-staff grand staff for piano-range material, with a manual override.
• Added automatic quantize-grid detection (1/4–1/32), with a manual override.
• Added a time-signature override.
• Added export to vector PDF, PNG, and MusicXML. MusicXML opens cleanly in MuseScore and Dorico.

Requires Ableton Live 12.4 or newer with Extensions support (the Extensions feature is currently in the Live 12.4 beta; tested on 12.4.5b3).
