Summary0010320: Behringer X-Touch One - LEDs are switched on but not off from Ardour
DescriptionI just got Behringer X-Touch One running 1.11.0 firmware (fresh from the website) and Ardour: (1:9.2.0+ds-1) from Debian repos.

I have to be on recent firmware because it fixes detection of X-Touch One on recent AMD Ryzen CPUs.

Did some tests with MIDI Monitor in Ardour and system. And it seems like Ardour is sending wrong Note Off velocity as far as I understand that. My X-Touch One is set to Mackie mode. Same in Ardour (Mackie Control) and profile for X-Touch One chosen.
Steps To ReproduceUse any action that lights the LED on X-Touch One. Use action again to arm/disarm Rec for a track or globally as an example.
LED is correctly switching On but never Off.
Additional InformationWhat Ardour monitor logged when arming track and global Rec:
     8934412 NoteOn chn 1 5f 00
     8934414 NoteOn chn 1 00 7f

     9154576 NoteOn chn 1 5f 00
     9154578 NoteOn chn 1 00 00

    12795370 NoteOn chn 1 5f 01
    12897500 NoteOn chn 1 5f 00

What I am able to use to switch the lights of global/track arm:
$ amidi -l
Dir Device Name
IO hw:2,0,0 WIDI Bud Pro MIDI 1
IO hw:3,0,0 X-Touch One

$ amidi -p hw:3,0,0 -S "90 00 7f" #on
$ amidi -p hw:3,0,0 -S "90 00 00" #off
$ echo "rec channel"

$ amidi -p hw:3,0,0 -S "90 5f 7f" #on
$ amidi -p hw:3,0,0 -S "90 5f 00" #off
$ echo "global rec"

It's not top-priority as I think is some quirk. But it makes usage so annoying that actually prevents normal use.

This is how it looks like after using buttons. Christmass tree basically. And I am not able to track what is on or off.

Ok I found something:
https://github.com/jackaudio/a2jmidid/issues/14

Compile with mentioned commit. But same result.

Could be a2jmidid bridge failing here. But standard PipeWire bridge is somehow not working at all.
