That dull thumping is the battlescape music. You can mimic it by getting a rubber band, cutting it and then stretching it end on end. Hold it close to your ear and start flicking it. Tighten or loosen it to change the pitch of the noise. Yes, the odd things you notice when you're bored.
Hmm, actually the rubber band sounds much more exciting ...
Midi music will sound different with different sound cards - they all come with their own midi instrument table. That's one thing I always hated about midi fles. My old 8-bit mono sound blaster compatible played the dos battlescape music beautifully - especially if you wore headphones. But when I later got a stereo 16-bit soundblaster, it became unbearable. A different computer with a similar type of card made it sound different yet again. It's really variable.
The windows version's battlescape music has always been terrible no matter what soundcard I've played it on.
I recommend copying GMGEO2.mid and replacing tactical.mid with it. Trust me, it makes tactical combat much more enjoyable.
