Poor-man's Kaossilator

kaossilator - puredata patch
Download here: kaossilator.pd
Video here: Youtube video

The Korg Kaossilator is a touch-pad synthesiser. It allows you to drag your finger across a touch pad similar to a mouse track pad on a laptop, and alter the pitch and timbre of a synthesised sound depending on your finger position on the pad.

Here's a picture of the original device (source: Korg, 2008)

I've created a software version of the kaossillator using a combination of Windows software. The first is from LiveLab who made an excellent piece of software called Touchpad2MIDI (mirror: touchpad2midi.zip).

Touchpad2MIDI needs a Synaptics touchpad!

We feed the output from Touchpad2MIDI to a PureData patch and then to a software (or hardware) synthesiser. Now you have a Kaossilator, but with sounds you can design yourself. (The real Korg Kaossilator has only a few preset sounds inside).

You could also use any other X-Y controller (and avoid using Touchpad2MIDI), feeding the data directly into the PureData patch.
