I recently acquired a xk-60 kvm version and I am trying to integrate it to vmix (v23.0.0.51).
I have no issue with using shortcuts via MIDI, but when i try and use the "Activators" to control the backlights I get some screwy results.
First, I have to enable "x-key Controller". If i only enable my controller from the list, nothing works.
Second, if I set the following:
Control: Note
Channel:1
Note:0 to 0
Event: Default
Type:X-Key Button LED (Blue)

it lights up the blue backlight behind button #1 ~ as expected
.... BUT...
If I change the color to RED, the backlight behind button #49 turns RED (and the blue turns off).

I have reset the device to factory default and reloaded the midi driver, but nothing seems to change it.

hmmmm
