pitch control for deejays?, anything out there? Options

[terrorphile]

i was over an my friends house and we hooked up my z5500 W/ sharp 3.10 to his mixer
and quicky realized we needed a pitch control of some sort so he could beat match to the records.
does anyone know of anything that might work?

i have x/qt working
but that about it
and im not that great with linux yet
(basically i havent had any luck what so ever with compiling anything ive tried so far)
if you can help, thanks in advance VERY MUCH!
