The Rhythmate was a tape loop based drum machine designed to accompany an organ player. the instrument had 14 tape loops with a sliding head that allowed playback of different tracks on each piece of tape, or a blending between them. It contained a volume and a pitch/speed control and also had a separate amplifier with bass, treble, and volume controls, and an input jack for a guitar, microphone or other instrument. The tape loops were of real acoustic jazz drum kits playing different style beats, with some additions to tracks such as bongos, clave, castanets, etc. The Rhythmate has a built-in amplifier and 12″ speaker.

In 1951, Harry Chamberlin used his idea of magnetic tape playback to create the Chamberlin Model 200 keyboard. The Model 300/350, 400, 500 and 600/660 models followed.
