Hi Mark,
on my Windows computer MIDIOX is running and I can see controller values when I’m touching the surface.
Do you have a MIDI monitor on your computer where you can see MIDI activities?
Installed a basic midi monitor and nothing from touch screen is showing up.
Keys, knobs, wheels, etc… all show midi data.
Touch Screen seems dead.
I’ve been emailing Nate back & forth in Asheville as well.
I’m back on v3.5, verified software is loaded properly.
Did a factory reset.
Even opened it up to check for a potential ribbon cable out of place (all seems fine).
The unit has remained in my control room for years without being moved.
