// The MIDI over USB interface to use
// Custom MIDI callback that prints incoming messages.

// Callback for channel messages (notes, control change, pitch bend, etc.).
// Print the message
Serial << F("Channel message: ") //
<< hex << cm.header << ' ' << cm.data1 << ' ' << cm.data2 << dec //
<< F(" on cable ") << cm.cable.getOneBased() << endl;

// Print the message
