After some re-writing, here we go… Before trying, make a backup of your Resources folder (even compress the whole Logic folder) first, as always.
I’ll start with my own and post all the updated themes that I get to know about. If you are a modifier, please inform me, i.e. “Jus”, about your updated theme at gearslutz.com!
Moonlight for Logic 10.1 (edit: Seems to work in 10.1.1 as well. It was ok in my short test. But always back-up before testing any theme.)
