[muso] Real time pitch/tempo shifting?

[Lee]

Here's the situation - I've got some WAVs on my laptop, and I want to be able to control the pitch and tempo as it's playing, at the same time. Preferably I'd like to be able to use a joystick to control it, but it's not strictly necessary.

Any hints? Thanks.
