It's possible that the system, due to the short duration of each piece, starts processing a file and of necessity moves on to the next piece and eventually runs out of resources. That's my bet and if so it's a function of RealTracks/Drums. I'd wager (if I'm right) that all midi files don't bring about that scenario. On the other hand, who runs all midi files all the time, (except for Notes?). I almost always have at least realdrums and usually a bass part too.

Good find, send your results to pgmusic and they will fix it one way or the other.....
