Here’s a track I did this weekend using a Kaoscillator and an iPod app called thumbjam.

The Kaoscillator piano and drum patch was fed into audiomulch to produced the distressed warbles and the strings were made with thumbjam.

IMHO it’s the best value music app you can get. The sampled sounds are very good quality and you can get some expressive phrases by tilting and shaking. If you haven’t already got it then download it, you won’t regret it.
