The main features of the omnichord are the organ like chord instrument together with the unique sonic strings, which are triggered using one of the 36 soft buttons (denoting each of the major, minor and 7th chords) and the strumplate.

This second instrument comprises the major chords clustered around complimentary chords. Starting at C4 the chords run in the following order - Dflat, Aflat, Eflat, Bflat, F, C, G, D, A, E, B, Fsharp. The organ chord is on the white key and the sonic string on the corresponding sharp. Not quite the true omnichord experience but you get the idea.

Just try it!
