This isn’t strictly a MIDI input hack; [Furrtek] pulled off an alternate input hack for the Kaossilator that he’s currently using with a MIDI connection. In its unhacked form the Kaossilator is a small touchpad-based sound manipulation tool. [Furrtek] sniffed out how the touchpad data is read and used on the little device. He then purposed an ATtiny2313 as the core of a circuit that spoofs those signals. The microcontroller now listens for incoming MIDI data, looks up the proper signal translations in a table, then outputs them to the Kaossilator.
In the video after the break you can see that it works perfectly, with no lag or noticeable problems. As we alluded to at the top, there could be so much more done with this. Since the ATtiny2313 is merely translating MIDI into touchpad signals, the input could be anything. The first thing that comes to mind is a dance floor that changes the music based on how many people are out there tearing it up.

I think this is great, maybe this can be integrated to the stock unit some day.
I think a MIDI-out hack would be more useful, personally.
That’s a great hack. Now someone bring it to the next level by using a pin of the microcontroller to read the frequency of an input signal instead of MIDI, so that one can drive the Kaossilator through a microphone or a guitar.
Awesome! ive been wanting to do this for the longest time. great job.
Hardcore hack!
A hack: “sync in” (5V Trigger) to sync the Kaossillator to another unit would be great!
