midi2

MIDI 2 is the next generation of MIDI, allowing bidirectional communication between enabled devices. This crate contains types and helpers for building MIDI-2 capable software in Rust. Specifications can be found at midi.org.

MIDI 2.0 is very much in an "alpha" state in the industry - operating systems have just begun to offer initial support for MIDI 2.0, and at the time of writing (Sep 2023) there are few (if any) devices that are available to send or receive MIDI 2 packets.

The goal of this crate is to allow device and application authors to encode/decode and interpret MIDI 2.0 messages in idiomatic Rust, with little overhead introduced by the underlying data representation itself.

Features:

• #![no_std]
• serialize/deserialize from universal midi packets (UMP)
• MUID generation (requires std)
• MIDI 2 AST

Todos:

• System exclusive helpers
• Capability inquiry (MIDI-CI)
• Property exchange (MIDI-PE)
• Conversion from MIDI 1.0 channel voice messages to MIDI 2.0 (increase resolution)

Help/Contributing

Contributions are very much welcome! Here are some good first issues:

• MIDI CI support.
• Property exchange.
• SMFCLIP2 file encoding/decoding
• Platform API conversion helpers:
  • MacOS/iOS
  • Android
  • Windows
  • Linux/ALSA

If you make a PR, make sure to update the authors field in Cargo.toml.
