-/**
- * @brief Virtual serial terminal.
+/*
+ * This is the Midi class.  If you are just sending Midi data, you only need to make an
+ *  instance of the class, passing it your serial port -- in most cases it looks like
+ *
+ *   USBMidi midi(channel);
+ *
+ *  then you don't need to do anything else; you can start using it to send Midi messages,
+ *  e.g.
+ *
+ *   midi.sendNoteOn(1, note, velocity);
+ *
+ * If you are using it to receive Midi data, it's a little more complex & you will need
+ *  to subclass the Midi class.
+ *
+ *  For people not used to C++ this may look confusing, but it's actually pretty easy.
+ *   Note that you only need to write the functions for event types you want to handle.
+ *   They should match the names & prototypes of the functions in the class; look at
+ *   the functions in the Midi class below that have the keyword "virtual" to see which
+ *   ones you can use.
+ *
+ *   Here's an example of one that takes NOTE ON, NOTE OFF, and CONTROL CHANGE:
+ *
+ *   class MyMidi : public USBMidi {
+ *     public:
+ *
+ *     // Need this to compile; it just hands things off to the Midi class.
+ *     MyMidi(HardwareSerial &s) : Midi(s) {}
+ *
+ *     void handleNoteOn(unsigned int channel, unsigned int note, unsigned int velocity)
+ *     {
+ *         if (note == 40) {digitalWrite(13, HIGH); }
+ *     }
+ *
+ *     void handleNoteOff(unsigned int channel, unsigned int note, unsigned int velocity)
+ *     {
+ *       if (note == 40) { digitalWrite(13, LOW); }
+ *     }
+ *
+ *     void handleControlChange(unsigned int channel, unsigned int controller,
+ *                              unsigned int value)
+ *     {
+ *       analogWrite(6, value * 2);
+ *     }
+ *
+ *   Then you need to make an instance of this class:
+ *
+ *     MyMidi midi();
+ *
+ *   If receiving Midi data, you also need to call the poll function every time through
+ *    loop(); e.g.
+ *
+ *    void loop() {
+ *      midi.poll();
+ *    }
+ *
+ *   This causes the Midi class to read data from the serial port and process it.
