7 months ago DOSBox Pure doesn't interface with midi devices directly. The midi settings of DOSBox Pure can be controlled by the "midiconfig" setting.
- If midiconfig is "frontend" it will use the MIDI output configured in the frontend
- If midiconfig is "foo/bar.sf2" it will load "{frontenddatadir}/system/foo/bar.sf2" as the GM soundfont
- If midiconfig is "foo/bar_control.rom" it will load "{frontenddatadir}/system/foo/bar_control.rom" and "{frontenddatadir}/system/foo/bar_pcm.rom" as the MT32 roms
When enabling the loading of dosbox.conf (in my case from a zip file), a lot of parameter seem to be supported correctly, but "mididevice" apparently is being ignored. Therefore, I am currently unable to pre-select "mt32" or "fluidsynth" via dosbox.conf. In RetroArch, I always have to go in the audio options of the core setting first and check if either MT32/CM32L or GeneralMIDI/GS is set set and change it manually, depending on the game´s MIDI support.
