Kas,

Thank you for clarifying a few things. There was a definite fallacy in my loopRec understanding. Your response cleared that up.

That comment made me scratch my head too after looking at it. I just botched my comment. Everything is working just as expected there except my commenting ability.

So, it appears that I do understand what is going on. My issue then is simply that I cannot call .clear() appropriately (.duration was my backup which also failed). Hopefully that will get fixed at some point, or maybe I can write a function to clear things out myself to see

if that works. Thanks again for all your insight.
