STEMSTAGE wiki

STEMSTAGE is the rhythm game that plays any song. Drop in a track and an AI (Demucs) splits it into stems. Every part becomes a playable chart: guitar, bass, drums, keys and vocals. Play with a controller, Rock Band / Guitar Hero gear, a DualSense, MIDI, or your real guitar, bass and keyboard.
