I had a problem that might be related.

I did add articulation marks, and then hairpins and phrasing and expression marks (pp and so on), and then found that some parts suddenly took a volume dive.  So far this sounds pretty much like Mr. Morgan describes.  But I have a follow-up question.

When I click on the Expression Tool, all the little square boxes pop up near the expression marks, as always, but in addition some extra little boxes are showing up ---often in pairs, and often close to a barline--- where there are no expression marks at all that I can see.  Now, I know that the file "remembers" the dynamics variations I make with the Mixer, (and possibly, also with the Aria Player mixer window), though I don't know how or where these changes are recorded.  I haven't removed the Human Playback feature, to check whether switching it off takes out the unexpected (and undesired) volume changes, as Mr. Morgan reports.  But I am intrigued with the empty little expression-type "boxed" (I wish a more apt term would come to mind), because I'd rather have no expression at all rather than bizarre expression changes!

Santu de Silva,

1) When you - in the Playback Controls - choose a Human Playback style, then the playback effect is created “on the fly”, every time you play the document back.

This means that the playback effect is not stored in the document’s MIDI data.

Just toggle Human Playback off in the Playback Controls, and there is no Human Playback.

2) You can also have the Human Playback effects saved in the document’s MIDI data, so that the effects will play, even with the Playback Controls set to no Human Playback:

MIDI Tool.

MIDI Tool menu > Apply Human Playback…

3) To clear the MIDI data for all those playback effects:

Edit menu > Clear Selected Items…

In the dialog box Clear Selected Items you can specify that you only want to clear MIDI data.

4) Playback effects can also be added via not displaying expressions.

These “not displaying” expressions will appear as those “extra little boxes”.

You can select these “little boxes”, and clear them.

Thanks for responding; this endorses my guess that clearing those empty 'boxes' might solve my problem!  I'm in the middle of something else, but I will check out this solution ASAC.
