I'm using an XK-68 Joystick as well as an AKAI APCmini. Eventually, I may phase out the X-Keys, but for now, I need them both.

Shortcuts -> Midi Settings (MIDI Devices) shows only "APC MINI" (attached image)

Shortcuts -> Midi Settings -> Channel Mappings sees 2 "XK-68 Joystick" devices from which to select (attached image)

Activators -> Enable Devices (Activator Devices) displays: "X-Keys Controller" AND "StreamDeck Controller" (which I do not own, but is Checked and does not retain un-checking) AND "APC MINI" AND "Microsoft GS Wavetable Synth" (attached image)

Activators -> Enable Devices -> Channel Mappings sees 2 "XK-68 Joystick" devices from which to select (same as second image)

I'm able to use both, setting the XK-68 Joystick to a channel greater than 1 (where the APC is seen on Channel 1). I've set the XK to Channel 15, as Martin suggested it might not cause the following issue if I did so...
All Shortcuts assigned to the XK work. All Shortcuts assigned to the APC Mini work.
All Activators assigned to the XK work. All Activators assigned to the APC Mini work.
Here's the trouble: Pressing any XK key will trigger the corresponding APC Mini key's activator. In other words: If I press the XK key 15:32, the APC Mini key 1:32 will begin flashing and remain flashing until I reset all. By the end of production, it looks like Christmas around here :).

Does anyone have any insight into this?

Thank you,

Chad
