This SK-1 has been seriously modified. In An Interview With Dr. Joseph Paradiso, Joe describes how he came about hooking this SK-1 up to the rest of his giant modular system:
"...this is an old SK-1 that I gave a
similar treatment to... The unit that interfaces to the modular system from the SK-1 is at right. Here I pulled out separate untreated voices and various control outputs. It sounds much more aggressive now.
"I figured out the whole keyboard scanning routine so I've completely mapped out what button and what key is what. The MIDI interface that I was going to build would have initially MIDI to CV, just a set of MIDI locations for these [buttons] so I can completely control all of these through MIDI, throw any switch or set any mode..."
