Supriya MIDI (26.4b1)

Supriya MIDI is a nanobind-based Python binding for the C++ RtMidi library, providing a simple cross-platform API for realtime MIDI input and output.

This library is heavily inspired by the venerable python-rtmidi library, which, at the time of this writing, hasn’t seen a release in a number of years. I started this library so that I could have pre-compiled binary wheels for Python 3.13+.

I’ve tried to keep this library’s API very close to its inspiration’s, but there are some minor differences:

  • Supriya MIDI uses integer enums for the API and error type constants.

  • Supriya MIDI’s MIDI message callback takes three arguments (message, timestamp, data) vs python-rtmidi’s two argument callback (message/timestamp pair, data).

  • Supriya MIDI has a single custom exception class vs python-rtmidi’s variety of exceptions.

Most code that works with python-rtmidi should be easily adaptable to Supriya MIDI.
