Okay, but how does the magic work?

Harmonimo keeps the workflow simple on the surface and deep where it matters. Play a note, stay in key, shape the harmony, and turn the idea into something worth keeping.

Play chords and melody at the same time.

Trigger full harmony with one hand while the other hand plays melody that stays locked to the key, so you can explore freely without falling out of the song.
