Hi Tim,

I don't know about all of those pairs, but in Piano Roll I'm seeing that some of your notes have an attack that starts 120 ticks before the notated note should sound. I'm not sure how you're entering notes, but that is the issue with the SA/measure 11 pair - the second A has an attack that is at -120 (you can see these values just by mousing over any given note while in Piano Roll). What that means is that the "note on" event for that note turns "on" 120 ticks before the notated note, which means it turns "On" while the previous note is still sounding, which in turn means that the sound goes "off" when the end of that first note ends and since there is no new "on" for the second note, it doesn't sound.

You can fix this by
(1) clicking on the note that isn't sounding and
(2) click on the "Snap as-performed attack to as-notated.
The note will then properly sound.

There are some other notes that sound properly (eg. C# in TB/m16 and A in SA/m16) that also have the attack at -120. If you let me know what method you're using to put the notes in, I'll test that here to see if there is a bug that is affecting the attack in some instances.

ttfn,
Sherry
