Crate coremidi 

This is a CoreMIDI library for Rust built on top of the low-level bindings coremidi-sys. CoreMIDI is a macOS framework that provides APIs for communicating with MIDI (Musical Instrument Digital Interface) devices, including hardware keyboards and synthesizers.

This library preserves the fundamental concepts behind the CoreMIDI framework, while being Rust idiomatic. This means that if you already know CoreMIDI, you will find very easy to start using it.

Please see the examples for getting an idea of how it looks like, but if you are eager to see an example, this is how you would send some note:

use coremidi::{Client, Destination, EventBuffer, Protocol};
use std::time::Duration;
use std::thread;

fn main() {
    let client = coremidi::Client::new("example-client").unwrap();
    let output_port = client.output_port("example-port").unwrap();
    let destination = Destination::from_index(0).unwrap();
    let note_on = EventBuffer::new(Protocol::Midi10).with_packet(0, &[0x2090407f]);
    let note_off = EventBuffer::new(Protocol::Midi10).with_packet(0, &[0x2080407f]);
    output_port.send(&destination, &note_on).unwrap();
    thread::sleep(Duration::from_millis(1000));
    output_port.send(&destination, &note_off).unwrap();
}

If you are looking for a portable MIDI library then you can look into:

• midir (which is using this lib)
• portmidi-rs

For handling low level MIDI data you may look into:

• midi-rs
• rimd
