## Article

#### Overview

The link provides "Arduino-AppleMIDI-Library", a library for implementing AppleMIDI on Arduino. This library allows you to transfer MIDI data wirelessly between an Arduino and a Mac or iOS device.

The library uses the Arduino Ethernet shield or Wi-Fi shield to implement AppleMIDI. The library includes functions for establishing an AppleMIDI connection and sending and receiving MIDI data. The library is also compatible with the "MIDI Library", a library for establishing an AppleMIDI connection between an Arduino and a Mac or iOS device.

You can use this library to create a variety of MIDI applications, including MIDI controllers, MIDI interfaces, MIDI sequencers, and MIDI drum machines.

#### What is AppleMIDI ?

AppleMIDI is Apple's MIDI network protocol, a technology that allows MIDI data to be sent and received over a wireless network. It allows multiple MIDI devices to connect wirelessly to send and receive MIDI signals. For example, a MIDI keyboard and a MIDI interface can connect wirelessly to send and receive MIDI data. AppleMIDI also provides high sound quality and low latency, making it ideal for professional music production.

#### For what, refer this project

The Arduino MIDI library allows you to create a variety of MIDI applications. For example:

1. MIDI controller: You can use Arduino to create a MIDI controller that generates and sends MIDI data. This allows you to control MIDI devices or software.

2. MIDI interface: You can use Arduino to create a MIDI interface for MIDI communication between a MIDI device and a computer. This allows you to send MIDI data to your computer, or receive MIDI data from your computer and send it to your MIDI device.

3. MIDI sequencer: You can use Arduino to create a MIDI sequencer that records and plays back MIDI data. This allows you to compose and play MIDI music.

4. MIDI drum machine: You can use Arduino to create a MIDI drum machine. This allows you to control a MIDI drum machine or receive MIDI data from a MIDI drum machine and send it to other MIDI devices.

5. MIDI LED lights: You can use Arduino to create MIDI LED lights that control LED lights based on MIDI data. This allows you to control LED lights to match your MIDI music.

#### Features

- Build on top of the popular [FortySevenEffects MIDI library](https://github.com/FortySevenEffects/arduino_midi_library)

- Tested with AppleMIDI on Mac OS (Big Sur) and using [rtpMIDI](https://www.tobias-erichsen.de/software/rtpmidi.html) from Tobias Erichsen on Windows 10

- Send and receive all MIDI messages

- Uses callbacks to receive MIDI commands (no need for polling)

- Automatic instantiation of AppleMIDI object (see at the end of 'AppleMidi.h')

- Compiles on Arduino, MacOS (XCode) and Windows (MSVS)
