This package exports 2 scripts:

• create-musescore-audio - an utility to generate audio files from MuseScore files with configurable channel volumes
• create-musescore-video - an utility to generate videos from MuseScore files
• score-util - used to generate videos with different audio tracks

All ideas and improvements are welcome via issues or pull requests.

Installation

npm i -g https://github.com/keijokapp/score-util

Requirements:

• Node 20 or later
• MuseScore 4 (possibly also works with earlier versions)
• ffmpeg and ffprobe

create-musescore-audio

Usage: create-musescore-audio [--audio=soprano=-13,alto=-13...] input.mscz output.wav

Creates a audio file from MuseScore file. --audio option can be used to override volumes of individual instruments. Channel names are part ID-s as defined in the audiosettings.json in the MuseScore file.

create-musescore-video

Usage: create-musescore-video [--audio=soprano=-13,alto=-13...] input.mscz output.mp4

Creates a video file from MuseScore file. It does this by extracting SVG-s and playback synchronization info with mscore --score-media. It then creates frame images, each being an SVG with a cursor line drawn according to synchronization data. --audio option can be used to override volumes of individual instruments.

score-util

Usage: `score-util [--audio=part1/soprano=-13,alto=-13...]...

Given that the utility is run in a working directory with the following structure

 /path/to/some-score
 ├─ some-score.mscz
 ├─ some-irrelevant-other-score.mscz
 └─ audio
    └─ part2.wav

It generates the following files:

 /path/to/some-score
 ├─ audio
 │  └─ part1.wav                  -- an audio file exported according to `--audio` option
 └─ export
    ├─ some-score.mp4             -- scrolling video with original audio settings
    ├─ some-score (part1).mp4     --              ... from part1.wav
    └─ some-score (part2).mp4

The --audio option can be used to export audio from the MuseScore file. It can be used multiple times.
