Matt the modulator picked this rather sweet 80’s Maplin Harmony Generator kit on ebay. Though nonfunctional after the initial assembly, a bit of rewiring got things up and running for the above-seen demo processing a Gameboy/LSDJ sequence. He was also kind enough to post the relevant schematics/article for those interested.

    That’s pretty cool. I wonder what it’d sound like with a guitar (electric/acoustic) wired up to it.

    I wonder how long until someone writesa a PIC or Atmel code equivalent for this…
