Rhythm Controller

The C 1650 is a multi-controller. It has 9 different modes that can be selected with a rotary switch in the center region of the panel. Also it has a "XY"-CV input for horizontal and vertical deflection and a MIDI IN/OUT. With these additional modes and inputs, the C1650 can he used as a simple 8/16 step quantizer and a MIDI-to-CLOCK-OUT and MIDI-NOTE-to Gate/Trigger device.
