This may also apply to all CDJ-2000 models. Version and Setup: Traktor Scratch Pro 18.104.22.168 macOS High Sierra 10.13.4 Reproduction Steps: Connect an XDJ-1000 MK1 via HID. Press PERFORM on the XDJ's screen. Load a Stem track in the deck. Observed Results: None of the hotcue buttons light up, and pressing them doesn't do anything. If you load a non-Stem track, and then load a Stem track, the hotcues of the non-Stem track are still lit up. Expected Results: When loading a Stem track, you should be able to trigger its hotcues on a CDJ/XDJ via HID.
