Greetings!
You’ll find the Music Box C++ sample program, filed under `music_box’, right here:
github.com/drivird/drunken-octo-robot.git
While porting the tutorial to C++, I also ported python class SoundInterval to C++. Look for it into file `p3util/CSoundInterval.cpp’.
I hope you find it useful and of course, constructive criticism is always welcome
Cheers!
