/*
 * USB MIDI adapter.
 * 
 * ---
 * 
 * To allow larger sysex packages, modify the Control Surface library as follows:
 * 
 * In:
 * src\MIDI_Parsers\MIDI_MessageTypes.hpp
 * change:
 * uint8_t length;
 * to:
 * size_t length;
 * 
 * In:
 * src/Settings/Settings.hpp
 * change:
 * constexpr size_t SYSEX_BUFFER_SIZE = 128;
 * to:
 * constexpr size_t SYSEX_BUFFER_SIZE = 320;
 * 
 * This should be fixed when Control Surface 2.x will be released.
 * 
 * ---
 * 
 * To use a different USB device name, edit hardware/arduino/avr/boards.txt in your Arduino IDE install using admin privileges.
 * Change:
 * leonardo.build.usb_product="Arduino Leonardo"
 * to:
 * leonardo.build.usb_product="..."
 * change it back after uploading the project to your Arduino device.
