Chord Lab

Chord Lab turns one finger into a full chord. Press any key and hear a complete chord instead of a single note, switch chord types and stack extensions for richer harmony, let Key Mode keep every chord in your key, and drive it all from your MIDI pads. The four base chord types and a bass voice are free to use forever — the pack unlocks the depth.
