New Transcription Model This update introduces a new default transcription model based on Transkun. (#6) Built on a transformer architecture, the same family of models used in modern AI chat systems, it provides better context awareness and improved transcription accuracy. The transcription pipeline has also been optimized with parallel CPU and GPU processing. Because the new model is more computationally complex, it may still run slower than the previous model on some devices. You can switch between transcription models at any time in Settings. Bug Fixes and Improvements • Improved the bug report view on iOS. • Transcription tasks are now properly cancelled when closing the transcription window on macOS. • Improved localized window names on macOS. • Improved efficiency when transcribing multiple files at once. • Fixed a sustain-related bug when importing MIDI files. • Improved the audio normalization algorithm. The previous version could be too aggressive and sometimes caused notes to be cut short.

New Features - New editing sidebar on iPad and larger iPhones in landscape - New Insert Note and Edit Pitch dialogs on iOS/iPadOS for easier pitch editing - New score markup functionality Improvements - General stability improvements and bug fixes to significantly reduce crashes and errors - Improved session resume after long inactivity (audio engine now restores correctly) - Fixed timing issues when importing MIDI files with variable tempo - Localization updates and fixes - Undo/Redo improvements: consistent labels and more reliable behavior - Fixed memory issues caused by unreleased objects and circular references - Undo history is now properly cleared when entering a new view - Fixed cases where some buttons could become unresponsive - Exported MIDI resolution updated to 4800 PPQ to improve compatibility with other software Music Score Editing - Smoother scrolling in the Engraving view - Engraving view now auto-fits horizontally when opened - Fixed top margin so content isn’t obstructed by the toolbar or Dynamic Island when scrolled to the top - Fixed an issue where shifting chords across measures could result in incorrect pitch - Clearer labels and improved Info/Help screens - Selection handling for edit actions + Undo/Redo is now more consistent - Moving notes can no longer creates duplicate notes in block chords - Fixed “Insert Note” placing notes in unexpected locations - Layout engine rewritten for better performance and fewer layout issues - Measure lengths are now correctly fitted on import - Added thumbnails for engraving files - Fixed a critical issue that could distort imported MIDI Localizations Thanks to agentic coding and WWDC 27, the app is now available in Japanese, French, and German. Please note: since the developer doesn’t speak these languages, some translations may be inaccurate. If you spot any issues, please report them to help us improve.

- Music Engraving view is now center aligned. - Add `Mark All Accidentals` feature - Add `Limit Duration` feature - Improve video rendering pipeline for OS26 devices. - Improvements and bug fixes.

New Features - You can now import MusicXML files. - When you import a MIDI file, the app will ask if you want to make music sheet or view piano roll. (Thanks to @vinhquach for the suggestion) #3 - You can now create octave shifts. - When you open a file created using a newer version, this app will attempt to open it. If it does, it will make a copy to prevent data loss. - Improves toolbar style on iOS. - You can now refine the note velocities in an imported score by providing the original audio. The app will analyze the audio’s dynamics and applies them to improve the score’s velocity data. Bug Fixes & Improvements - Fixed crash when you shift part of a beam to other measure, then shift it back without using redo, then redo. - Distance between two staves is now adjusted automatically. - Fixed the bug where selecting multiple notes only plays the last note. - Engraving Engine improvements. - Resolved FLAC import issue. (Thanks to @vinhquach) #2 - Fixed potential write issue on macOS. (Thanks to @vinhquach) #4 - You can now long press undo / redo buttons in EngravingView to view action name.

What’s New • Smoother engraving export and a new Settings & Info menu • New option in Settings to disable GPU for CPU/Neural Engine–only processing • Auto-normalization is now enabled by default (your existing custom setting is preserved) • Now supports transcription workflows via the Shortcuts app • Improved post-processing descriptions to make features easier to understand • Refined engraving editing style, context menus, symbols, and measure configuration view • Improved keyboard shortcuts and Undo toolbar • “Steepen Beam”, “Flatten Beam”, and “Merge Into Chord” now produce better results • Edited MIDI files in MIDI Workspace now automatically replace the originals to keep your projects tidy Engraving document compatibility • Stem steepness information is now stored in a new format. If you open a file created with this version in an older version of the app, stem steepness data may be discarded. • When you open older documents in this version, their existing stem steepness information is preserved and migrated to the new format. Stability and bug fixes • Fixed issues with Music Engraving stem editing when only some notes in a subdivision are selected • Fixed cases where playback could continue after leaving the engraving view or closing it while playing • Fixed a soft-lock when opening a file with Express Mode enabled • Fixed undo/redo issues after refreshing and a potential crash when undoing • Fixed selection edge cases and potential file import bugs • Fixed a visual issue with sheet coloring after inserting a new measure • Fixed various localization issues Reviews • The app may occasionally ask for a review at an appropriate moment to help others discover it. You will only be asked once.
