I've compiled a package of MIDI files from
Warcraft: Orcs and Humans, maybe it'll be useful to you people?
I have used
WarDraft to extract the XMI files, and then converted them to MID with WinAmp (the built-in converter in WarDraft produces a slight increase in playback speed for some reason). In fact, there are three sets of XMI files in Warcraft, designed fro sue with different sound hardware settings. I've converted the set that is used with General Midi, and supposedly has higher quality (the MIDI pack found at the
Game music base seems to use another set).
