Hi Noel,
Sorry for the delay responding. A non-music project had me away from the studio for a couple of days. (I can tell you that furniture moving as a recreational activity is highly overrated.)

Thank you very much for this detailed step-by-step, which of course effected the solution perfectly. I just knew when I did my OP that I was gonna learn something, and to my delight, I did, courtesy of you. I've always just swapped real players in and out of tunes indiscriminately (rarely ever even made a style out of the new combos as I don't tend to reuse them). So I may have had a few behaviors like this in the past that I just worked around.

Now I know there are a ton of parameters in the actual player position itself that can affect other players swapped in. So I'll be keeping an eye on those in the future as things to tweak!

I know I join the ranks of many on this forum whom you have helped. We all appreciate your generosity with your vast knowledge of this amazing program.

Best,
K-Toons
