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.

My Gakken SX-150

This is my Gakken SX-150 coming directly from Japan. The SX-150 is a analog synthesizer with LFO, pitch envelope, frequency cutoff, resonance and attack/decay. The pitch is controlled by a wired pen and a resistor-strip. It has a build-in speaker and a mono 3,5mm mono-jack. The SX-150 comes as a kit and a Japanese manual. The kit is very easy to assembly. You just need a screwdriver and some patience. It also takes a little training with the slide-controller to find the correct notes which I show you in this short clip:
