Cross-platform, realtime MIDI processing in Rust. This is a friendly fork with small changes required for vendoring the crate in Firefox. It will go away as soon as we will be able to vendor the upstream crate.

midir is inspired by RtMidi and supports the same features*, including virtual ports (except on Windows) and full SysEx support – but with a rust-y API!

^{* With the exception of message queues, but these can be implemented on top of callbacks using e.g. Rust's channels.}

midir currently supports the following platforms/backends:

• ALSA (Linux)
• WinMM (Windows)
• CoreMIDI (macOS, iOS (untested))
• WinRT (Windows 8+), enable the winrt feature
• Jack (Linux, macOS), enable the jack feature
• Web MIDI (Chrome, Opera, perhaps others browsers)

A higher-level API for parsing and assembling MIDI messages might be added in the future.

API docs can be found at docs.rs. You can find some examples in the examples directory. Or simply run cargo run --example test_play after cloning this repository.
