Thanks and Yeah the multi channel soundcard is a deffo must ......... the NI Audio Kontrol 1 seems to be ok for this purpose and the Indigo one for laptops.

Think i will be using this alot with an external mixer.

Have an Ecler Hak 360 at the moment but this might just tempt me back too a another Allen & Heath XOne 32 ..... regrets selling the last one i had ............... and current budget wont stretch as far as an Xone 3D which has the soundcard and hardware controls for Traktor / Ableton built in (£1400 would be another 2 weeks snowboarding).

Any tipson getting the analyze function to be more accurate would be welcomed. Would be nice to leave traktor in the knowledge that the beats are locked and free me up to focus on additional layering with my turntables.
