Then I looked at how they send data to the serial port for MIDI OUT in the library, and saw that they use a slightly different syntax: serial_.print (b, TYPE). So I tried adding that instead, as follows. I've included an extra snippet that shows how they're doing it, for context. My line is the one with the asterisks. I assumed that I could ignore the type argument, since I'm just passing the (int) variable c straight thru.
