Probably being an utter numpty here, but the last time I used virtual DJ with my MC6000 MK2 I had to do the entire gig on deck 1 & automix as I couldn't get deck 2 to play through the MC6000& the only volume control I could get was through the master.

I've looked in settings & set deck 1 to ch 2 & deck 2 to ch 3 on the mixer, but still no joy.

Any ideas what I'm doing wrong?
