MIDIPolis Io Jupiter 4 MIDI retrofit

"Io User Manual
1. Introduction
Io is a MIDI retrofit system for the Roland Jupiter 4 synthesizer. It consists of two boards that can be used either parallel or individually.
One of the boards is the Keyboard Assigner Extension and it enables MIDI control over pitch note, pitch bend, cutoff frequency, volume and portamento. It also synchronizes the arpeggio to MIDI clock and has two powerful LFOs on pitch bend and cutoff frequency. LFO settings are storable and recallable.
The other board is a complete replacement of the Jupiter's original patch programmer microprocessor with full MIDI specification and lots of functional enhancements.

Roland Jupiter 4

via this auction
"to Quote Phil Oakey of the Human League 'the Jupiter 4 will be tatooed on my heart for ever' The specs really don't prepare you for what this synth is actually capable of."

This is a genuine analogue Poly synth with real analogue oscilators (the Junos had DCOs Not VCOs) and filters, for BIG 4 voice pads and Stacked unison lead and bass sounds This JP does NOT have MIDI, but you can buy the IO kit and fit it very easily yourself for 98 Euros.

A few things that make this so special:
2 Envelopes per voice, one for Filter, one for VCA
There is a Fiter modulating Sample and Hold circuit which is clocked to the arpggiator for some great sequencer effects for undulating rhythmic pads.
Random Arpeggiator (THIS is the synth all over Durans RIO )
The LFO alos goes into the audio range for some great FM style sounds.
That massive Roland Ensemble Chorus Circuit..."
