Well, the only problem there is that the space is vastly increased if I do so. The midi count so far is 23, and rising; it'll probably be around 40+ before it's done. The game's download size would be increased by probably between 50-80mb if I used mp3s. That's why I'm looking for some sort of alternative.
My other choice would be to convert the midis over to a tracker format like .it, .mod, .s3m or .xm, but I don't know if DBPro accepts them. I'm also not thrilled with the way programs attempt to convert midis over, as they generally do an awful job of it.
