This is an OCaml package that provides bindings to the portmidi library.

It uses the excellent ctypes library to generate the C-stubs which should help minimize the bugspace.

Installing

opam install portmidi

Status

Open/read/write works. Reading sysex messages is untested so far.

Upstream C library

The upstream C library is at https://github.com/rbdannenberg/portmidi though your distribution may ship an older version. In the future, this project will likely vendor the C library.
