FabFilter

I am using a master chain of Fabfilter plugins (latest versions of Pro-Q3, Pro-DS, Pro-C2 and Pro-L2) on Compound clips in Final Cut Pro. I use the Compound Clips to group all the edits in a video and to place the final master audio processing for the whole video.

The FF plugins are giving me lots of issues like bogging down FCP to the extent that it is showing the spinning beachball a lot when working with parameters in a plugin. Especially Pro-Q3 is giving me issues.

The biggest issue is that I can't change switchable parameters after I have inserted the plugin, changed parameters and closed the plugin window. That is if I open the plugin again I can change switchable parameters but once I play the timeline, these parameters jump back to their previous values. With switchable parameters I mean parameters that are buttons like the Limiting algorithms (Style) in Pro-L2 or changing the Zero latency to Natural Phase in Pro-Q3 etc.

Even if I only use FF plugins in the chain (my chain also contains a plugin from Acon), it will give me the same issues.

The plugins have no issues running in Logic Pro (also AU like FCP) on the same Macbook Pro. They also run perfect in Pro Tools on my Mac Pro. But that's AAX of course.

Is this problem known and is there anything I can do to try and fix this?

I'm running Final Cut Pro on a Macbook Pro 2021 M1 Max with 64GB RAM and 32 GPU cores with the latest MacOS Ventura 13.3.1.
