Arduino MIDI Library

This library adds MIDI I/O communications to an Arduino board.

Features

New : USB MIDI Device support with MIDIUSB.
Compatible with all Arduino boards (and clones with an AVR processor).
Simple and fast way to send and receive every kind of MIDI message (including all System messages, SysEx, Clock, etc..).
OMNI input reading (read all channels).
Software Thru, with message filtering.
Callbacks to handle input messages more easily.
Last received message is saved until a new one arrives.
Configurable: overridable template-based settings.
Create more than one MIDI interface for mergers/splitters applications.
Use any serial port, hardware or software.

Getting Started

Use the Arduino Library Manager to install the library.
Start coding:

#include <MIDI.h>

// Create and bind the MIDI interface to the default hardware Serial port
MIDI_CREATE_DEFAULT_INSTANCE();

void setup()
{
    MIDI.begin(MIDI_CHANNEL_OMNI);  // Listen to all incoming messages
}

void loop()
{
    // Send note 42 with velocity 127 on channel 1
    MIDI.sendNoteOn(42, 127, 1);

    // Read incoming messages
    MIDI.read();
}
