Made this version with Thru Hole parts and a Arduino Nano. Schematics are heavely based on Mutable Instruments schematics.
Note: panel hole for button might be a bit to big or small (depends if you use buttoncaps)
I made this for my own and would like to share it with you. I'm doing this as a hobby so expect support to be like that to ;) Everything at your own risk..
Some info on my website that might help http://www.quinie.nl/?p=17
