MuScriptor — multi-instrument music transcription (MAESTRO mirror)
Mirror of MuScriptor (Kyutai × Mirelo), laid out for MAESTRO's download-on-demand loader:
| path | upstream | notes |
|---|---|---|
small/ |
MuScriptor/muscriptor-small | 103M params, CPU-capable |
medium/ |
MuScriptor/muscriptor-medium | 307M params, default |
large/ |
MuScriptor/muscriptor-large | 1.4B params, most accurate |
shared/beat_this_final0.ckpt |
CPJKU/beat_this final0 |
tempo / downbeat tracker (MIT) |
shared/MuseScore_General.sf2 |
MuScriptor/assets | soundfont for the A/B audition (MIT) |
Weights are byte-identical to upstream (sha256-verified at mirror time). Inference code: muscriptor/muscriptor (MIT).
