It's a collaboration from both sides in order to integrate support. Currently, we provide MIDI support for the XDJ-1000MK2, but they have not integrated HID support and we don't offer an official TSI file, so that means the mapping is up to you.
We just announced Traktor certification for the CDJ-2000NXS2 and DJM-900NXS2 today, so hopefully our teams will be working to include some of the other products, such as the XDJ-1000MK2.
