X-touch mini does not default to channel 0 for the Rx channel as is assumed

[phrrk]

The manual currently says this about the X-touch mini.

These devices should be in Standard Mode (not MC). Layers A & B are somewhat supported, however, since the device does not send a notification when switching between layers, and since lights (both under buttons and the pattern used around the rotors) are set based on which layer darktable believes is active, everything will only be updated completely after you press or turn something in the "new" layer. Default settings are assumed; if any have been changed they can be restored using this [X-Touch Editor](https://mediadl.musictribe.com/download/software/behringer/X-TOUCH/X-TOUCH-EDITORv1-21.zip)

With my new controller I could get it work in most respects, but the button lights would not reain on as expected. After much messing around I realised from the darktable code that the Rx channel was assumed to be zero. On checking using the X-touch editor I realised that the controller as delivered (or after a factory reset) was using channel 11 (or 12 as given by the editor as it uses 1-16 numbering). After using the editor to change the Rx channel to 0 (1 in editor speak) all works well. This means that the manuals statement that default settings are assumed is incorrect and instead the editor has to be used to explicitly change the Rx channel.
