Those setups look really nice!
Mine is more simple but does what I want it to do.
Made it mostly because I wanted more analogues for ClOD.
3 multiturn pots for trim and 4 regular pots for other use.
16 double toggle switches = 32 buttons.
Nice to put commands on tagged switches so I don't have to memorize keyboard commands.
Multiturns for trim is great, I use geared scale so I can see the position.
The extra holes because I used pushbuttons at first but those were of inferior quality -bought cheaply from e-bay.
All are connected to the excellent card from Leo Bodnar.
