siridjen 0:03c039c2a00d 15
siridjen 0:03c039c2a00d 16 Connect the button to ground and input pin, there is no need for a pull-up resistor, it is enabled internally.
siridjen 0:03c039c2a00d 17 Enable Secondary to send secondary CC messages. (used for mapping momentary switches in Ableton)
siridjen 0:03c039c2a00d 18 Enable debug to print to serial port instead of midi.
