This question is twofold. One: do I need a Traktor audio card (like an Audio 10) for DVS control if I have a USB mixer such as a Pioneer 900, Denon 1700, A&H XoneB4, whatever? Or can Traktor receive timecode input from the audio interface in the mixer?
Two: Supposing I'm using CDJ-900s or 2000s which have HID support, can I set my audio device to whatever I want and still have scratch control? When using an aggregate audio device to route audio from my DAW to Traktor, I found that while I could still get input from my timecode vinyl, I couldn't use it for timecode control.
