I've spent far too long looking at Cyberdecks on HaD and Reddit, I think. It's influencing my decisions with projects like this. It's not a bad thing. Ha ha ha!
One of the main issues I've had with this project is space utilisation; fitting two separate Pi systems and still having enough space for a foot controller with plenty of controls for the two systems.
Cyberdecks always seem to have a screen mounted off-centre on the back of the keyboard, and it creates space for a fair sized keyboard input, so I'd like to explore the same here.
To that end, I'd like to look into mounting the Pisound and a much bigger enclosure for footswitches for it, then look to mount the Pi touchscreen setup to the back of the pedalboard, using two bolts through the pedaltrain board and another two through the footswitch enclosure.
