MIDI

If you're running Windows, MIDI ecalls should work out of the box! On Linux, however, you need to install a software synthesizer and a soundfont. I recommend following the Timidity++ guide until the section that explains how to run the daemon.

Note that systemctl start timidity may fail with the error "Failed to start timidity.service: Unit timidity.service not found.", in which case you may try systemctl --user start timidity instead, or run timidity -iA as a last resort.

FPGRARS takes a --port argument that specifies the MIDI port to use. You can find the port number by running aplaymidi -l and finding a TiMidity port. Although in my experience some of them might not work :)
