RMR: RtMIDI, reduced

Hello and welcome to RMR documentation.

RMR is a rewrite of RtMIDI project’s ALSA 1 part from C++ to C with GLib (it uses both GArray and GAsyncQueue for input). It is made as a personal experiment for use on embedded devices.

It is using the Sphinx documentation generator with Hawkmoth extension.

I will probably rewrite Jack support, as well, but I don’t have access and motivation for rewriting Mac / Windows parts.
