Hi Kbird,
rotary switch works as 12 single switches. But witch 1 common contact that you have to use as common ROW (or COLLUMN) and you have to use 1 diode for every switch position = 12 diodes. But MMJoy2 knows only 10x10 matrix button so either you use only 10 position of rotary switch or use board with shift registers to connect this rotary switch and you need no diodes then. It is the best solution. Or this rotary switch you can set for only 10 positions easily, there is a washer with such jut and move this washer to position for 10 and you have 10-pos rotary switch.
