@Noobielectrix I've added an update to my answer. I think you missed out on using the minimize option that is available to you in Logic Friday. Hopefully, this helps. (I'll +1 your question with this additional added work product. Thanks!)

| Jan 6 at 16:03 | comment | added | periblepsis | There is a discussion of something like this here. It counts up or down, though. It it looks like he did another one here that is just a down-counter, starting at 9 if I read it right. | |
