MuScriptor is an open multi-instrument music transcription model developed by Kyutai and Mirelo. It converts audio recordings into note events, MIDI, or engraved sheet music with instrument information, and provides a locally hosted web UI, command-line interface, and Python package. Its architecture is a transformer decoder-only model; small, medium, and large variants are distributed through Hugging Face and downloaded and cached automatically after authentication. Sheet-music output uses MuseScore 4 or newer to generate MusicXML and PDF scores, including instrument-specific and tablature PDFs. The project can be run with uvx or installed from PyPI, and the model weights require acceptance of the CC BY-NC 4.0 license. The README notes that transcription works best with a steady tempo and performs significantly worse on rubato recordings.
