on an ipod touch, where i could load a song form my ipod library and pitch it?
ive been considering getting an ipod nano so i could sample shit when i'm not near a turntable, but if its possible to get pitch control with an ipod touch then i'd be willing to drop a little extra cash on one.

I'd highly recommend djay...

...it's a turntable in your pocket. Really well made piece of software too!
