That sourceforge project looks familiar.

I had started that little project some time ago. I believe I had some trouble with decoding IT samples and the other developer helping lost interest which brought it to a grinding halt. I don't believe a project that is source only exists, not for Pascal. But you could start one if you were so inclined. I could dig up some of my old sources for the player I started. It was able to load older S3M and MOD files and play back the samples from a list. It's an old Delphi project, but I'd have to find it.
