After reading other threads about people using a mixer into a sound card, I think I'll just give up on the USB interface approach and go back to my Behringer 1002 FX into a good sound card- problem is then, how do I record MIDI- my Turtle Beach PCI soundcard has the 15 pin port my midi adapter needs, but I guess some of the M-Audio cards also feature MIDI connectors.

I just tried loading up PTPA 12 and got the exact same results as with RB, so I'll be putting the Presonus USB on E-Bay tonight, then buying an M-Audio soundcard.

Thanks for the suggestions!
