S4 and Xone K2 for ableton/traktor setup

[tombarton]

I have tried countless times to configure a stable ableton and traktor combo using my s4 and its built-in soundcard but have always run into problems, either with unwanted feedback or the channel faders failing to control the output of each deck. I presume this is something to do with the soundcard of the s4 as I know it is possible using something like the audio 10 interface.

I was considering buying an Allen and Heath K2 as an extra effects controller and wondered whether its in-built soundcard would help my situation in any way?

Don't know if its possible with one computer, id guess so but i wouldn't know how. Use the K2 as a live input into the S4 and use it as a send/return kind of thing using ableton for effects.

Look up the Chris Liebling interview on here for ideas!!
