Xone k2 / 23c Allen and Heath

If you are getting a k2 and a 23c mixer then you have 2 soundcards. You are better off buying a k1/kontrol x1 which is cheaper. And using the 23c as your sound card for traktor.

I used to use a kontrol X1 and a mixer for traktor and can DJ off of that fine. Was using it in a club for 7 years with no problem.

If you are using traktor I’m sure their is a way of mapping a button or knob to change the key of a song easily enough on a k2/x1
