Hello to all Traktor fans, I have a small problem, maybe you have a solution for me...I have 4x the D2 controller and am trying to get all 4 to work...unfortunately only 2xD2 work with Traktor 4...since I wanted to save myself the hassle of switching back and forth from deck to deck and don't use a second computer, do you have any idea how to get the 4xD2 to work with a Traktor 4? Many thanks...
