Reply to Two ASIO Devices confilicting? MC 3000 + Xone K2

Hi Folks,
first of all thanks for trying to help me out - this is my problem:
I have recently acquired a new Xone K2 and it does not seem to get along with my MC 3000 as far as output routing goes. When I connect both devices and start Traktor the Denon Asio Driver doesn't make a sound (yes I have checked the outputs and speakers in Traktor but not even the monitors/ headphones work).
Anyways as soon as I change it to the "MC 3000 Shared Mode" it starts working, but of course this is not what i want since it as a bad latency. I have tried to set it up and connect the Xone:K2 afterwards and it always works until the point where Traktor recognizes the device and it completely distorts all audio. It's hard to explain therefore I caught it on video:
If you have any advice please help me!
Regards, Joseph.
