just to let you guys know what happened with our setup:
after different problems with different bugs in the software (i will open a seperate thread for this later), we managed to make it possible.
when using the XONE DB2 as soundcard its as easy as this:
put your Turntables into the XONE mixer, set the mixer to "Line" and the mapping to "USB".
Connect the XONE with your PC via USB (of course install drivers for the DB2 before you do so), start Cross, and set it up like I did in the picture:

The CD-Players are easy to set up, just connect them via USB with your PC and you can use the "LINK"-Button on your CDJs to choose which deck to control with it.
As for the Traktor AUDIO6 setup, its almost the same, but you can`t use 4 decks, since the Audio6 only has 3 outputs, so you are limited to 3 decks.
