Other games when I run them use my windows midi mapper when I set them to General Midi.. Xcom surprisingly doesn't. It's baffling. I want to hear what the game is "supposed" to roughly round like using the Yamaha XG software I got on sale

I mean, my version even has the sounds working in the intro video. The version that was recoded for Windows (which I also have with that retro issue of PC gamer from back in the day) even lacks those sounds.
Here's how it sounds normally with fm synth music. I don't want to record the general midi music but I DO want to listen to and enjoy it with a more symphonic and emersive feeling (though the FM synth is still pretty moody and creepy in the game).
