"Motorgan is an electromagnetic/electromechanical organ based on 3 dc motors of different size. The speed of each motor is controlled by voltage changes via touch keyboard with 24 keys. Keyboard is split into 3 parts (registers) for each motor, so it's possible to play chords/polyphonic lines by taking one note from each register. Electromagnetic fluctuations produced by motors are picked up with a single coil guitar pickup. It's possible to tune every key using potentiometers, to make any kind of music by tuning the combinations. It's not the easiest instrument to play and it takes some time to adapt to it.
