Midis?

I was wondering if their was anyone knows how to get midis to play in TGE. I am aware that this would require engine changes, but my dad is hopefully going to be buying me an Indie license for my birthday, which is in a few weeks.

But, if you don't, what's a great program to convert midis to oggs?

Advantages : Very small file size, so you'd be able to transfer them very quickly.

Disadvantages : No voice/lyrics. Midis might suck for some people.
