This is very simple...
use the Traktor Mapping from dj Hairless here at the Forum. You will also find it at dj tech tools...
This Mapping is for internal Mixing in Traktor.
- Set the XDJ-RX to MIDI Mixing and Traktor to 2Deck + 2 Remixdecks.
- connect the F1 and controle the Remixdecks. If you set the Chanelfader by Mouse to Max you can use the 4 Slot Volume Fader at the F1 for the Remixdeck level....
