Incompatibility in Logic Pro
I cannot use any preset of Pro Q4 or Saturn 2. It always says "Incorrect file permissions or corrupt preset file." and I am not even sure if Saturn 2 even works anymore. Like I can see that the overall headroom decreases when I engage the saturation, but I can't hear the difference anymore. HELP!!

This seems to be an issue with the files offloading from your computer and onto your iCloud when you have iCloud syncing enabled for your documents folder. You can download the preset to your local machine again by clicking the download icon in Finder. The presets are located there:
Documents/FabFilter/
You can also right click on the folder and choose "Keep Downloaded" so the files will not be removed locally again.
Please let me know if this resolves your issue.
