Live Duet Harmonist
Play chords and an AI accompanist answers with a jazz comping bed — rootless voicings and a walking bass that locks to the rhythm of your playing, not a fixed metronome.
A 12-bin chroma front end matches your chords against 36 templates (maj / min / dom7), waits a 160 ms settle so the bed is anticipatory, then comps with jazz voicings and a walking bass synced to your onsets.
