#define COMPILE_MIDI_OUT 1 // Set this setting to 1 to use the MIDI output.
#define COMPILE_MIDI_THRU 1 // Set this setting to 1 to use the MIDI Soft Thru feature
// Please note that the Thru will work only when both COMPILE_MIDI_IN and COMPILE_MIDI_OUT set to 1.
#define USE_SERIAL_PORT Serial1 // Change the number (to Serial1 for example) if you want
// to use a different serial port for MIDI I/O.
#define USE_RUNNING_STATUS 1 // Running status enables short messages when sending multiple values
// of the same type and channel.
// Set to 0 if you have troubles with controlling you hardware.
#define USE_CALLBACKS 1 // Set this to 1 if you want to use callback handlers (to bind your functions to the library).
// To use the callbacks, you need to have COMPILE_MIDI_IN set to 1
#define USE_1BYTE_PARSING 1 // Each call to MIDI.read will only parse one byte (might be faster).
