Thank you, food for thought. I've seen a handful of MIDI to CV boxes out there. Where would one find the pinout for the ARP Jones connector so that I can get the CV signals properly laid out?

I recently stumbled onto a ARP 2600 system that is missing its requisite keyboard. All I have is the oscillator/control module. I have a few questions: 1. Judging from pics it looks like not any old keyboard will interface with this thing. Is that true? 2. Is there a way to make a modern controller ...
