The Omnichord was designed by the Suzuki Company in the early 80th, to be an electronic autoharp, that would enable anybody to be a musician right away, learning curve about 5 minutes.

This is how Suzuki seems to imagine the average Omnichord player ....

The first Model, OM-27

It had chord buttons for nine major minor and 7th chords. Only why? The chord-generator chip could produce all twelve keys, - if you get the matrix layout right....

Anyway, it´s a perfect target for circuit bending.

a rare brown OM-27 with manual and training-cassette, and it comes with a rubber guitar pick for the "sonic string" board....

The successor OM-36 or System One. It features all twelve keys, major- and minor-7, augmented and diminished chords. Now it has 10 rhythms, but unfortunately, you can´t mix them anymore by pressing more than one button, too much logic involved already. There is also a different controller chip-set.

OM-84 or System Two. Now with two sounds, chromatic keyplay and an obscure chord memory function, that I haven´t figured out yet, mail me if you got the manual. The main sound board is the same as with the OM-36

Later models underwent a cosmetic redesign and are most likely ROM-plers. Model 100

Model 150 looks quite the same and still has 10 rhythms but also 10 strumbar sounds. Suzuki seems to have given up on the chord-memory idea...

The last of this area, the dark Model 200 also has 10 rhythms and 10 strumbar sounds. But now there is MIDI...

Omnichords are still produced. Nowadays they are called Q-Chords and they have MIDI and sample ROM. To me this looks like a Klingon weapon . . .

bend the Omnichord, that´s where the real sounds wait...
