I actually experienced a similar problem with an XTONE pedal. And now I finally ordered a good old FCB1010 here because I heard it’s even more bizarre.
I have previously made some work on making customer controller mappings, but never quite finished it. It’s able to actually draw a visual reproduction of your controller in the patch bay and each button you define can be scripted with Lua. Its not high priority right now, but will eventually arrive at some point.
