Thanks for all the input guys,

I have a bit of an update, but first let me say that I had tried the MIDI Panic thing before initially posting this without success.

A few more things have since popped up which may help narrow things down (and I will paste this in the OP, for the newcomers who are reading from the top).

1. It's not just MIDI styles, or even files/sings with a single MIDI track I have this problem with. RTs are now having a audio note from one the random tracks sustaining throughout even where no MIDI is present at all.

2. (and this one is the oddest). I found that if I mute and unmute the melody track in the mixer panel the note immediately disappears--this is regardless of whether or not that slot is actually populated with a track(!)

So, in short, it appears that this is not a MIDI thing, and I'm getting a strange hunch that this may be a driver thing? I just updated all my drivers yesterday, so I have no idea why I'm getting this hunch in the first place...

Anyway, thanks again for all the kind offers of assistance!
