Hi, Tim, Sherry:
The stuck notes are the ones where the two tenor voices overlap, at the A-natural on beat 2 of bar 46 and at the Ab on beats 1 and 2 of bar 51. Same thing happens on the second beat of bar 59 and the first two beats of bar 60. There may be others.
Having the two voices playing the same notes at the same time there leaves one of them with a missing note off.
I've tried rebuilding the phrases with new notes of different lengths, but the missing note offs (notes off?) re-appear.
Can't think of a work-around, because it shouldn't be a problem -- the two voices should handle their own separate note off commands.
That's what you get for working your tenors so hard, Tim.
David
