Yes.

@tttapa can you please give me an example of row to use CD74HC4067 MUX with CCButton?

tttapa commented 5 years ago

Just like this example: https://tttapa.github.io/Control-Surface/Doc/Doxygen/dd/dcc/md_Getting-Started.html
Then just pass the pin number to the CCButton contructor:

CCButton button = {mux.pin(0), address};

Thank you @tttapa, congratulations for the library. It's awesome. I turned a broken POD HD 500 into a MIDI controller with the Control Surface library. Just need to make expression pedal works, it's using an IR transmissor and receptor.

Do you need help with the expression pedal? Do you have a picture, drawing or schematic?
