Hi,
I’m having the same problem, and I may have found something.
I noticed that when I’m listening to playback then click elsewhere for playback to move to that location, it messes up the articulation/expression playback. BUT, if I press stop then move the cursor to a new location then start again, it seems to work ok.
However, there are still occasional glitches where it will just play the wrong articulation for seemingly no reason…hope this helps.
