[Musicbox] OSC via Serial

musicbox.ino

// This code runs on the Teensy
// Uses https://github.com/CNMAT/OSC
// It sends a bundle, 0 - 1 for each musicbox
// In order to make sure that there is clear start
// and stop to the packets SLIP is used:
// https://en.wikipedia.org/wiki/Serial_Line_Internet_Protocol
// As this sketch is incredibly minimal, the
// OSC library above is effectively the documentation.

// A MAX example is available at:
// https://github.com/CNMAT/OSC/tree/master/Applications/MaxMSP/examples
