Blood maybe, try googling 3D midi games.

What is the most hardware demanding game, that support (General) MIDI music? I am thinking is there any purpose building a pc with Pentium III 1Ghz, Octek s370 mobo with one ISA slot and put a midi card on it? At this point my fastest pc with ISA have Slot A Athlon 550Mhz. I got plenty gpu's & ram's to choose from, so it is all about cpu.

Tell me more about the Octek made S370 mobo. Didn't know they were still alive in that era.

Anything that support high resolutions will be demanding enough for a fast Pentium III 😀

I second Blood. It is probably the most demanding DOS game I own, and does have good General MIDI support. Another one that is right there with Blood is US Navy Fighters. Crank it to 800x600 and turn air, water and land textures on and it bogs down a bit even on a K6-2 550.

Look at DOS games from 1996/97.

Jane's ATF probably, though its 1994 predecessor was also very hardware demanding

Doesn't Comanche 3 support GM or am I remembering wrongly?

If not, then I suspect the answer would probably end up being one of those hackish games in the rush to go 3D that would have been stuck with MIDI music.

I think Armored Fist 2 had GM support as well (excluding the menu music) and that's a svga voxel hell with loads of lookup translucencies. so that also qualifies

Extreme Assault also deserves a mention for being high color and pretty while having midi 😀

F-22 Lightning II and System Shock (in SVGA) come to mind. When it goes to ISA slot, BX boards are your best bet, although you can also find Pentium 4 motherboards with ISA slots. When it goes to AMD, I think the ISA slot board that supports the fastest AMD CPU available is Epox 8KTA3+, although it only comes with one ISA slot.

Unless if it supports 3D acceleration, where 3D accelerator like 3dfx Voodoo or nVidia TNT takes over the texturing and filtering jobs from the CPU.

I don't think it was implied to be exclusively dos though but I can't name much demanding Windows-based MIDI-supporting game either...but you could mention F-22 Raptor, which is more or less Lightning 2 with noisy software texture filtering.... and EverQuest.

In case of Windows it's easier --you won't really need an ISA mobo to have nice GM sound in games. I remember playing a Windows game named Captain Comics in Windows 95, which has GM music, then I played it using WinGroove soft synth. The sound was great.

For Win9x even P4 would have the use. In case you want DOS games mostly, then take into account that faster CPU may reduce your DOS compatibility, as 1000EB may be downclocked to 500 MHz as the lowest.
For demanding GM games look at latest there.

If we're talking mainstream games, my guess would be the Build engine games too; Blood, Duke Nukem 3D, Shadow Warrior, Witchaven, etc.

As a reference, an Athlon XP 2400+ on a KT133A mobo is enough to run Blood smoothly in 1280x1024. With a T-bird 1200 in the same computer, I had to run it in 1024x768 to get decent FPS.

Thanks to you all for the good answers. I did not know, that a quite many simulator games used midi. I mostly played the build engine games, AoE1, Quake2, Carmageddon, GTA1 etc. back in 1997 on P166MMX. I might build that PIII after all in case I play those simulator games at some point or DN3D kill a ton maps on hi-res, I have never played those maps before. The mobo is Octek Rhino va694xb-acp rev.a1
