JKJ CV-5 MIDI CV Converter / Audio Processor For Sale. This little box features lots of great tools for interfacing your vintage gear with more modern gear. MIDI to CV and gate, DIN sync, LFO, portamento, pitchbend, aftertouch, velocity, controller outputs, there's even a mono to stereo panner. Wow! We got it from someone who used it with his Electrocomp EML-101, since it's one of the few boxes that will drive it.
