The Xeen midi files are in some unusual format (I have no idea), as well as encrypted in the Xeen data files. The ones below are the decrypted versions, but I still don't know how you can actually play them. If you can decode them or know someone who can, I'd like to know how you get along.

I put a few of them on the web

Also I contacted Tim Tully (the Xeen music man) a while back about them, but I can't really remember what he said. If you want to talk to him, you can probably google his email address. I think last time I got through to him by a series of forwards through other agencies.
