So I have a Traktor Kontrol S2 and I am running Traktor Pro 2.5 on my Windows 7 laptop. My problem is that if I cue up a track on deck A while having a track playing in deck B, with the cross fader all the way to the right, if I try and play the track that is loaded on Deck A the sound still comes through with the cross fader all the way to the right. I have tried recalibration for the cross fader and also have restored the default settings to the controller. I have not applied any special mapping to my S2 and all the settings seem to be default settings. I'm really scratching my head on this one and I feel like there is a simple fix to it. Any suggestions would be greatly appreciated!
