My name is Lorzone and I am in the process of getting a new setup. I just ordered a pair of cdj-900s and I already have a behringer ddm4000. I want to hook my setup to a laptop and run traktor pro. I saw on a post that you seemed to have success hooking this up. I was just wondering what audio interface would work? I saw on one post that something as simple as an M-audio Uno would work. Would I just need to set up my mixer as a midi player and then hook up the cdjs to the mixer and have them running in pc mode? I'd appreciate any help. Thanks!
