DJM900 NXS Help. Routing audio from Traktor Into Ableton

[hrtbrkd]

I was wondering if I could route audio from Traktor into Ableton then Route that audio back to the DJM900 NXS souncard so it can be played out from the mixer? This is what I have done so far.

Now the problems I am having is it's mono sound and I can't hear Deck B from traktor. The next issue is it's not routing the sound through Traktor anymore or even through the DJM900. It uses the soundcard, uses traktor deck A and sends the sound to Ableton, when I record I am seeing both traks being recorded but can't hear both sounds. Hope someone can help. Thanks in advance.

So this is what I have so far. I am now able to route the Traktor Audio in Stereo into Ableton, Have ableton apply VST effects, master the music, clean up the sound and mix each track on it's own seprate channel in ableton , Then route the music to my DJM-900 NXS using a Mini Jack to RCA.I am using two different programs one to Sync Midi clock and BPM tempto from Traktor (Master) to Ableton (Slave). The program I use to create the virtual cables is Jack Control Center aka Virtual Audio Cable Kit. Does this sound right to people? Is this the best set up possible? BTW this is for Windows 64bit.
