Hello.
I bought a DDJ-RX controller and before buying I'd thought that it was compatible with the Traktor Pro 2 but I was wrong. I searched the Pioneer forums and a staff told me that Pioneer would not release an official mapping for DDJ-RX. After that I tried mapping for my new controller but beside the basic mappings (start, cue, syns etc.) I couldn't map the FX s, performance pads etc.
Could anyone who knows about mapping help me doing it or help me to find a full DDJ-RX mapping for Traktor Pro 2?
Thank you.

Now made a custom version of my mapping to the DDJ-800. There were very small differences.

2019 DDJ-800 v6.3.3 - mapping for Traktor Pro 3 and 2 - DJ Estrela
This is a demo of my traktor mapping to the DDJ-800. This is the same mapping as my DDJ-1000 with very minor adaptations (described below).
All features, all pads, jog scratch and jogFXs taken from the 1000 work fine in the 800. Please see that video for a full description.
These are small differnces that I fixed on this specific 800 mapping:
- mixerFX selector buttons require 2x presses to toggle (instad of being hold style)
- beatFX selector has new MIDI codes, and now works as expected
The following are other differences that I did not customized (yet):
- The Auto-Loop button is missing. Instead please press 'Loop In long hold';
- To exit loop, press shift+exit
