ScorePrep v1.0 Release

ScorePrep v1.0.0

First stable public release.

ScorePrep transforms messy piano transcription MIDI (from tools such as ByteDance Piano Transcription, MT3, Magenta, etc.) into clean, notation-friendly grand staff MIDI for MuseScore and other notation software while preserving the original performance as faithfully as practical.

Philosophy

ScorePrep is designed as a piano transcription cleanup tool, not a general-purpose MIDI editor.

Its goal is to automate the tedious cleanup normally required after AI transcription so that the resulting MIDI imports cleanly into MuseScore (or similar notation software) while remaining musically faithful to the original performance.
