Processing and ChucK 'Hello World' demo

Update 15 September 2007: I have fixed the code so it will now run on Windows too; when a new process is created it now uses Runtime.exec to set the working directory to data.

My first Processing and ChucK demo had a major pain - you needed to start and stop ChucK from the command line. No longer!

In this new demo Processing sends out messages to monitor.ck. When this program no longer receives any updates it shuts down ChucK. So starting and stopping ChucK is now done by Processing.

The demo sends mouse coordinates (x and y) to a ChucK application, helloworld.ck, to change freqency and harmonics of a 'Blit' (STK band-limited impulse train).

This is how the demo looks like (listen with headphones):
