The crazy couple of months turned into several more (although they have been the good kind of crazy). I have not walked away from trying to addressing the above issues. I'll spare you all the stories.
Anyway, I have heard back from both Behringer and Novation. As soon as I get many more repairs knocked off the bench, I can get back to this issue.
FWIW, I have made tremendous progress in honing my vintage analog repair skills.
