Reply to Need Help with a Set Up

So I have 2 Numark NDX800s, the older ones, before they had the USB audio, and I have a Behringer DDM4000 mixer. The question I have is how would one best set this up to a computer, so that I could use Tracktor. Right now I do everything with flash drives and it is becoming a pain trying to keep all of the music organized since the NDX800 can't read more than a 4Gb stick. It would be greatly appreciated if anyone had any set up of gear suggestions that would make that work. Thanks in advance.
