so a single cpp file can only have one class in it? all functions are considered part of the class?
Perhaps I am misunderstanding... I want to split my midi related stuff out of my main sketch into a midi.cpp file... part of this midi related stuff is the class, but not all of it. Am I to understand that I cannot have a global function and a class in a single cpp file?
extern MyMidi midi(Serial);
in midi.cpp would take care of things then right?
extern MyMidi midi;
