I’ve added a “Files” page, with wiring diagrams and firmware (binary and source.) Currently there is a “generic” wiring diagram for the DMC-PCB as well as the M9 DD-6 Hold Mode firmware and the “test” firmware that ships with new boards. I will be posting the 6-button M9 looper control firmware this weekend once I do some more testing on it. I think it will work with the DMC as-is but I would feel better if I made sure it worked before posting.
Files page is here.
