Reply to So what exactly do I need......

So I just purchased a Xone62. Im currently running the traktor S2. Im a past turntable user at heart and the S2 just didnt give me that warm fuzzy mixer feeling, plus I wanted control of all four decks.

So my question is as follows, I know that ill be purchasing a couple of X1's for controlling traktor, and ill want to route all four decks into the 4 channels in the mixer, but what kind of sound card will suffice. Will the NI audio 8 do the trick? thanks for any help.
