I’ve had so much trouble with the modular PCBs that I’m thinking of just starting over using a 6582 baseboard from smash. I already have my frontpanel made up and don’t really want my MBSid in the PT10 case. So before I go and get myself really stuck, is there a wiring guide for a custom CS using the 6582 baseboard? I searched the wiki and the forums, but didn’t find anything.
However, this might not be the best way for you, if you really only want a minimal control surface. The alternative is to use the DIN/DOUT modules at the bottom of the MB-6582 base PCB as “normal” DIN/DOUT modules, i.e. connect switches, encoders and LEDs directly to these.
