Right exactly, so the problem is conceptually very simple... just a missing note off. There aren't extra messages.

Andrew,

There are the same number of ON and OFF messages in the file (227). In the cases I checked, there is an OFF corresponding each ON. But you could look at the lines that I marked and make the interpretation that one of the OFF messages got delayed till after the next ON message was received. (As if an OFF got lost in a traffic jam on the MIDI bus!) Lots of possible interpretations.
