Arduino MIDI Library

Arduino MIDI Library is a lightweight, free and open-source library under the MIT license, which can be implemented by developers into their software projects to facilitate MIDI I/O communication with Arduino serial ports.

The tool offers support for not only all Arduino boards but also clones with an AVR processor. With its help, end users will be able to rapidly exchange MIDI messages, including Clock, System messages and SysEx.

Arduino MIDI Library is compatible with Software Thru for message filtering. Thanks to its help, callbacks can handle input messages easier. The latest received messaged is stored until a new one arrives.

The library can be configured using custom settings based on initial templates. It supports OMNI input reading for all channels and makes it possible to create multiple MIDI ports for programs that handle merging and splitting. Any serial port, hardware or software can be used.

In addition to the source code, the downloaded package includes examples with basic I/O, bench, callbacks, dual merger, input, MIDI USB, simple synth, and RPN NRPN (set the controller number, send plain values or increment/decrement directives). The library software package can be installed with the aid of Arduino's library manager.
