I once put in a midi file by accident, when I was playing around with the editor and realized it would play in the game, instead of being left out of it and it sounded good at the time. I can't exactly remember because I was a child back then who was very young, so my memory is a little iffy, but is it possible that Midi files can play in staredit instead of trying to find a long .wav sound file to play music?

I am very curious and wanted to know if somebody discovered this answer. I will find midi files if I have to and I imagine that's probably going to be a little bit difficult. So, does anybody know if midi music files are usable in StarCraft's campaign/level editor?

No.

Dammit! I was hoping for a maybe or yes... Aw well.
