Multi-instrument transcription
Question: holding a multi-instrument AMT model fixed, does training on more multitrack data (SPDMX) beat Slakh2100-redux on Slakh-test note F1?
We follow the MT3 / YourMT3 mixture→multi-instrument MIDI setup. SPDMX supplies
aligned mix.flac + mix.mid for songs with ≥2 stems
(~2,734 song-hours). Arms: Slakh-redux | SPDMX multitrack | optional union, matched steps.
Primary eval: Slakh test note F1; secondary: SPDMX held-out.
Metrics and audio examples will land here when the pilot finishes.
