So I isolated a single track little ditti that demonstrates the problem.  It would require Aria Player 1.0.2 (2009) and I'm using GPO violin 1 Sol KS, though I don't think it's sample dependent.
 
So if I play the ditti straight through, it's fine.  If I start it at a certain location, it's off pitch.  Nothing else in the track except a mod event for volume.
 
I suspect the answer is get a newer Player, though, it's not that old and has always treated me nice.  Don't think I can attach a file here anymore, can I?
