I see. I'm using a Teensy++ 2 and on a breadboard to prototype this project when I connect from the ground pin to the bottom rail on the breadboard (-) it seems that all the holes on that rail indicate ground, so i think 1 wire from the Teensy ground pin and the ground wire on each stop attached to it, it would work. It certainly would be easy to test it out anyway. What has always confused me is when I see and hear the word ground bus wire or common, I'm not understanding where a ground wire stops or starts -- it just always appears as one wire in the end (i.e. like a pedalboard, with one wire being the common) and then as each pedal is pressed continuity is established between 1 pedal and the common, and when is all put together that 1 common wire goes to the ground pin on an encoder and the other 32 go to the numbered pins. I'm probably not being very clear as when it relates to electrical signals and such I am not knowledgeable as to the appropriate terminology used. In my head "connected to common or ground" means the thing that all switches have in common is perhaps the bottom wire on the switch needing to be grounded, and the "identity" of the switch would the pin on the encoder that the other wire would be attached to.
