2) I just thought of this: Just run two empegs into a mixer. Except for the speed control, that would totally fulfill your requirements, wouldn't it? And if you pre-processed the audio files to fall into a specific BPM range, then you wouldn't need the speed control (unless I'm misunderstanding how DJs do their jobs).

Dionsys is right on this point. You have to be very exact with the BPM's.

The other point i was trying to get across is that all the music is in one place. If I used two Empegs then I would need to load two Empegs, which defeats the point a little ... not to mention the cost !

Thanks for your thoughts guys
