Adding some more info -- in the areas I'm concerned with, the attack and duration values in piano roll show as +0/-7. Just as a wild guess, I tried changing these values to +0/+0 for one test and +0/+1, to get a little overlap, for the other, and I can't say if I can detect any difference. Of course, I have no idea if the thought of lengthening the duration would have any beneficial affect. I thought it might smooth out the performance a little, but I can't hear it.
