Feature: FM synth music playback via libADL about systemshock HOT 8 CLOSED

In case it helps, GZDoom is an example of a project that integrates libADL alongside several other music playback options: https://github.com/coelckers/gzdoom/tree/master/src/sound

from systemshock.

I've been playing around a bit with this and have it playing the Midi music over at https://github.com/Interrupt/systemshock/tree/adlmidi

It sounds amazing in some places, and not so great in others. There's also some basic XMI midi support in there which kinda plays the SS XMI files, but it plays all the tracks at the same time so it's just a wall of noise right now with those files.

I dunno about using a soundblaster soundfont but the soundtrack with a Roland SC-55 sounds great

I use fluidsynth to get this sound when i play Doom in Gzdoom.

LibADL isn't a soundfont, it's an entirely different kind of synth for playing music. The sounds characteristic of FM synthesis can't be replicated with a soundfont.

As for getting the (totally unrelated to FM synth) SC-55 sound, there are a couple of soundfonts out there that apparently do a good but not perfect job. Currently Shockolate uses SDL2_mixer to play MIDI via whatever is available on the system, and it's probably possible to point that towards an SC55 like soundfont.

Modern midi support really can destroy the soundtrack, the Soundblaster version sounds so much more like the electronica it was trying to replicate: https://www.youtube.com/watch?v=dcOVe2rX_80
It's worth a shot playing midi through something like this to see how it sounds once we've got the XMI soundtrack working again.

The XMI support in adlmidi has been getting better with some recent commits so I've been using that as a base to unearth the layered XMI track playback along with the Music AI system that controls all of this. This work is on branch https://github.com/Interrupt/systemshock/tree/adlmidi-xmi

It seems to be sequencing the tracks correctly now in my proof of concept but libAdlMidi seems to either be playing the file for too long before looping, or there's some loop points in the XMI files that aren't being handled properly since there's a long period of silence at the end of the music snippets.

Have been taking another stab at this: #163

This is in now, for the most part.
