Relay Performer

Relay Performer is an interactive music performance system which enables relay performance between human pianist & AI pianist. It requires MIDI port connection (eg. Disklavier) and uses built-in audio device for real-time stream processing. The online time warping (OLTW) algorithm is implemented in this system, based on the paper MATCH: A MUSIC ALIGNMENT TOOL CHEST by Simon Dixon published at ISMIR2005.

Tested on Python 3.12 (conda)
