What I use for a soundfont is a conversion of GM.DLS to SF2, so it's that god awful excuse that Microsoft used for a default MIDI sound set, just the raw samples from a Roland SC-55 with no filter stages or anything.

The filename of the SF2 references the "Roland SCC-1" but that's just a SC-55 on a ISA card as far as I'm aware.

Also, Daedra Lord enemies will make a laugh that's probably the same stock studio sound that Raven Software used for when you pickup weapons in Heretic.
