Roland MC4 Computer

From Wikipedia, the free encyclopedia

The Roland MC-4 Microcomposer was an early multi channel sequencer. It could be programmed using the ten key numeric keyboard or a synthesizer keyboard using the keyboards control voltage and gate outputs. This sequencer was released before the advent of MIDI, and viewed by some composers to have more perfect timing.[1]
