Hi again Big D,

P.S.
quote: "Because the glissando markings can't be sounded, don't listen to the .not file, instead just follow along while listening to the midi file."

Maybe they can be sounded. Try playing around with editing the "as performed" attacks in each note in the gliss, moving the attack to the right one click at a time (1st note=no change, 2nd note=one click, 3rd note=2 clicks, 4th note=3 clicks, etc.)
