Fabfilter Pro L keeps crashing Final Cut Pro X

Anybody else getting multiple crashes when using Pro L with FCPX? It happens to me very often and it is a shame, since Pro L is so much better than Apple's own limiter plugin.


We're not aware of a problem with FCPX. Can you send us a crash log via email (use the Contact link at the bottom of this page)?

I have just installed Pro L on my FCPX machine and it is crashing also.


Hi Pete,

We have now identified a problem with FCPX which could cause the crash. I've sent you an e-mail about this now!

I am getting the same problem. Is there a workaround or fix?

Hi Kevin,

We've implemented a fix for this, which will be introduced in a minor update soon! As a workaround, I think that disabling the 'Background Render' option will prevent these crashes...

Hi Floris,

Can you comment on whether the stretched GUI problem in WaveLab 8.5 will be solved too in the minor update coming soon?

Justin Perkins

Hi Justin,

Yes! That will also be fixed!

I have a simliar crash issue with FabFilter plugins in Final Cut Pro X. I often use De-esser, EQ, Compressor and sometimes Limiter - I don't know which causes the crash.
The other day it seemed like it was Q3. It kept crashing once I opened the project. After removing the Q3 and then re-adding it to the clip, it stopped crashing.

I'm dealing with all fabfilter plugins dropping from FCPX still. Any solutions?

Adding Pro Q3 to FCPX 10.5.2 Timeline (audio) crashes FCPX (Catalina 15.7) invariably
