grig/Lobby

Oh okay. There isn't an end-to-end solution to playing multitrack midi files in grig yet. The main missing pieces are a) a class that subclasses MidiIn but that reads from a midi file and uses timers to dispatch the events and b) sample-based synths appropriate for general midi (but if you're okay with fm synthesis, there is that already). Also if you just had the first thing, you could open a MidiOut to any system virtual instrument (like Windows has) or a virtual port to a synth you run in another process (like fluidsynth).

Also note that games these days almost never have software synths built into them because it takes processing power to handle that. And modern systems don't have sound chips to handle it like in the old days. It just so happens though that I'm doing a talk about this in a few weeks! So what you want to do is unusual but also something I encourage (with caveats). It's definitely a more complicated approach. Not simple like you might assume from the fact that websites used to always have midi soundtracks. I'm the 2nd to last talk on the last day https://www.gamesoundcon.com/schedule
