@baer > The XDJ-RX was never intended to be a controller, the primary form and function of the unit is as a stand-alone unit. Only due to popular demand by users was a TSI file ever released, as well as rekordbox integration. Users weren't satisfied with how the display was used within rekordbox, so the engineers updated the communication method to HID, as a result, the TSI file and Traktor integration no longer work with the current firmware.
I'm sorry you're unhappy with all the advancements that the engineers have made due to requests by your fellow RX owners, but as mentioned in the other topic, which was closed, you are fully able to map the LEDs yourself so your RX operates as you expect with Traktor.
