Really cool! I did something very similar a couple of years ago - added a 25 key keyboard, sub-oscillator, pulse wave and envelope generator. I did all of the keyboard stuff with microcontrollers though, which allows for MIDI I/O. That reminds me, I need to rebuild the electronics for it as it's a complete mess internally Wink

The one infuriating thing about this forum I keep noticing is a complete lack of youtube demonstrations.

I'd love to see this in action.
