hmm. which sample specifically? this track was actually written with (old version, since I've been lazy to update) Open MPT, but I'd recall playtesting it with Hippoplayer and Pro Tracker 3.62 on Amiga 1200.
edit: ah, nice catch with the unused patterns. I usually cleanup my s3xmodit songs from unused crap after finishing them, but for some reason I have not remembered to clear those few extra patterns this time.
