An analog rhythm machine released by Roland in 1979. Also known as the CR-78 CompuRhythm.

The unit offers 34 preset rhythms (some accessible via bank switching) and 11 "variations" for fills and breaks. Controls for volume, tempo, accent, balance and fade-in/out are available.

Programming your own beats is also possible, 4 of which can be stored in the CR-78's memory. Unfortunately there is no quantization, and only 4 instruments can be used in a pattern. There is an ability to kill single instruments from the rhytym with 4 buttons.

On the back panel there are two outputs with different impedance plus trigger in/out jacks. Two pedal inputs are also available; the first allows the pedal to be used as the start/stop button, while the second is for programming.
