There's a tutorial here: http://chuck.cs.princeton.edu/doc/learn/tutorial.html http://chuck.cs.princeton.edu/doc/learn/tutorial.html These days synthesizers, samplers and whatnot are naturally just software. If you want to have fine-grained control of how synthesis, sampling or other sound manipulation is done, it's often useful to have a programming environment specifically made for that. The competitors that I mentioned to ChucK in my last comment are the best known environments for such. I personally use ChucK mostly to process MIDI instructions and reroute them to a separate synthesizer or to send control signals to a sequencer. For instance, in one case I wanted to play a pattern of notes at an increasing tempo stretched to the track's tempo using a specific function of time so that the notes would be in synch / out of synch with the original in a predictable pattern. Doing that was reasonably easy to hook up with ChucK.
