Using the Analog Experience the Laboratory controller

I’m attempting to use the Analog Experience Keyboard Controller to easily switch MIDI channels via the snapshot buttons. My most important application for this is in live performance, so I can’t have a lot of shenanigans to change output MIDI channels.

None of the instructions I’ve found seem to work. I have attempted using MIDI Control Center and manually changing the settings on the physical keyboard to no avail.

Has anyone here done this? What’s the secret?

thank you!
