G-FLEX'S PROFILE

I've always considered MIDI rather limited and archaic in terms of a distribution format; you never even know how it's going to sound on the user's computer. Besides, download time for a game isn't as much of an issue these days, I guess.

MOD tracks are nice (smaller filesize than, say, MP3, without the equivalent audio compression artifacts and with consistent quality), but of course you can't use those with RPG Maker as far as I know.
