S2 - S2 MK2 Qeastion

I was just wondering if the S2 works with the Traktor DJ App or is it only the S2 MK2 that is compatible?

I believe only the MK2.

Please try posting a new thread in the proper forum next time, Justin. ;)

So is that correct? Only the MK2 works on the ipad with "Traktor Dj" NOT the original S2?

Yes.
