That's just the original DOOM music (first level, E1M1) on a Sound Blaster AWE32 or something similar, so it's completely accurate.

MIDI FTW.

GUS Extreme, MT32, and SB16 Pro (or AWE64 Gold) with a Wave Blaster I or II, and you're set for the basic flavors of MIDI. Maybe an Ad Lib for extra vintageness and a Turtle Beach Multisound Pinnacle too.
