Reply to Kontrol S4... Would I be wasting my money....

If I bought one of these to hook up to my current setup of 2x CDJ1000s, RMX 1000 and Behringer mixer?

I want this piece of kit, as it looks sleek, and I have heard some good things.

However, I only want it to control Trakotr with, and don't want to move solely to using a controller.

Would this be a good way forward or should I consider other options?
