Traktor compatibility

Is it possible: Yes.
Is it good: No.
Traktor is closing its system, so that mainly native instruments controllers work. So there will be significant downfalls when using Traktor on anything else and you really need a deep knowledge of the software to make it work.

So my recommendation would be:
If you are fixed on Traktor, get a Traktor controller from Native Instruments.
If you stay with the Pioneer go for Serato instead, it will work much much better.
