/***********************************************************************
* ARDUINO_MIDI_DUAL FIRMWARE -
* TheKikGen Labs - 2017.01.16
*
* Based on :
* . The wonderful LUFA low-level midi lib and examples by Dean Camera
* (http://www.fourwalledcubicle.com/LUFA.php)
* . Inspired by HIDUINO from Dimitri Diakopoulos
* (http://www.dimitridiakopoulos.com)
* . Inspired also by dualMocoLUFA Project from morecat_lab
* (http://morecatlab.akiba.coocan.jp/)
*
* Compiled against the last LUFA version.
USB ATMEGA8U2 ATMEGA 328P
