Explore diatonic chords, inversions, bass and arpeggios, with multi-track MIDI export.

How to use

Choose a key and scale, edit the progression, audition inversions and export the chord, bass and arpeggio tracks.

Know the limits

A harmonic sketchpad, not automatic analysis of an uploaded song. MIDI needs an instrument to produce sound.
