Hello ports@,

This is a new port for munt which provides a library mt32emu that can
emulate high-quality synthesizers like Roland MT-32, CM-32L, LAPC-I.
This library can be enabled by dosbox-staging with the attached diff
(it's actually enabled by default; had to disable it without the munt
port) to use this emulated audio device. It's also picked up by
games/exult, which is why I'm including a diff here.

For audio to work, ROMs from the synthesizers are needed to produce the
sounds. dosbox-staging has some detailed info about those [1] and how
to enable MT-32 MIDI. The address for the device has been 330 when
software asks for it. I tested this successfully with a few games in
dosbox-staging (Tie Fighter, Realms of Arkania: Blade of Destiny, and
Jagged Alliance). The instructions for Ultima VII via games/exult are
here [2].

The port also includes (GUI) applications to work more with these
emulated synthesizers for those with an interest in making MIDI music.

I've checked several other games/emulators that cover that era of MIDI
music to see if they pick up libmt32emu (dosbox, dosbox-x, scummvm,
sdlpop, shockolate), but that's not the case. We might need to be on
the lookout if anything else from that era picks it up.

ok for munt? (the diffs are for testing it with dosbox-staging or exult)
