MidiVox SX-150 Mod

Narbotic posted a nice mod for the Gakken SX-150. As you may already guess, I could not resist to try it out. It's a very small modification on the arduino-based MidiVox and because it worked so well, I decided to build everything in a eurobox. The MidiVox is connected to the stylus of the SX-150 and control it via CV.
