The Roland Jupiter-4 (JP-4) was an analog synthesizer manufactured by the Roland Corporation between 1978 and 1981. It was notable as the company's first self-contained polyphonic synthesizer, and for containing digital control of analog circuits (termed "Compuphonic" by Roland), allowing for such features as programmable memories and voice assignment modes.
Io MIDI retrofit kit
László Kővári aka "Covariance" developed a MIDI kit and CPU replacement for the Jupiter-4. This two-part kit expands the Jupiter-4's patch memory from eight to sixty-four and also allows recalled patches to be dynamically modified (the original 8048 disallows editing once the patch has been saved). In addition to MIDI all sliders and switches can receive MIDI control messages, the arpeggio can be synced to the MIDI clock as well. A second LFO was also added which is even faster than the Jupiter-4's original LFO."
