I recently purchased a Traktor S2 Kontrol and MF3D. After spending the past few days getting comfortable with the ins and outs of the S2, I wanted to add a MF3D into the mix. I downloaded a few of the traktor mf3d maps to try out but if I run Traktor software with both the MF3D and S2 plugged into the computer at the same time, the S2 drops out. Traktor says there is no S2 connected. I have followed all of the steps precisely as shown in the 'loading and creating mf3d maps for traktor' video, but nothing seems to counteract the fact that the S2 gets knocked out by the MF3D. Even rebooting the S2 wont do anything unless I disconnect the MF3D from my computer's USB, and then the S2 will work like a charm again. Can anyone offer any suggestions or insight into what I might be doing wrong? In the midifighter utility, the software is set to traktor and four banks mode. The mf3d works fine in ableton, but I cannot get it working in traktor at all. Help! Thanks!
