PRO Q4 causing hanging in Logic 11.
Hi all.
Im having an issue with Q4 causing lots of plugin unstable errors, slow loading times, freezing, hanging etc.
I've meticulously tested my sessions by removing all components/audio units and wiping the cache, restarting and then adding each plugin back in, one at a time and testing the session and how it responds to loading, buffer changes, saving, changing audio interface etc and everything points to the Q4.
As soon as i re-introduce Q4 all the issues come back.
Im on macOS 15.3.1 / Logic 11.1.2 / q4 4.0.1 / M1 Max MacBook Pro.

Hi Benji,
Is there a crash report you can send us? Sometimes opening Logic in Rosetta mode will give you a crash report when running it natively will not.
