You can do that, just scan your ass and load the file as an instrument in Renoise. It won’t sound very good though, but what do you expect from a scanned ass?
Hmmm, that’s a good point. As(s) a matter of fact i tried with Melanie Fronckowiaks’ butt, it didn’t sound that good right away, but when i looped it i got some awesome effects, especially when i moved the loop area while the butt was playing.
That made me think there should be a way to automate the loop, sweeping it back and forth, you should try it, it really does sound awesome, like Aphex Twin awesome!
