I am going to be doing a house party for some friends, and while I don't have my own powered speakers yet. I am in university after all. I wanted to output sound on both the A and B channels so that I could use two decent PC speaker systems together. I wanted to know if there is a way to set this up on Traktor. I don't have a mixer I only have a midi controller, which has it's own soundcard. If I could route sound through both channels on the NI Audio 2 how would I route it so that pre-cueing comes out the internal soundcard on my midi?

thanks in advance.
