Problem with VST insert effects

Hey everyone.

I have a question regardingVST Effects in the mixer inserts.

I use mainly waves-plugins, and some (not all) of them don’t remember when I change any settings.
After closing and reopening a project, the settings on some of the plugins are set back to default. Some remember the changes properly.
The plugins that are affected are always the same.
Any ideas?

Best,

Stephan

PS: if it’s of interest: I‘m Using the latest Dorico on an 23 MacBook Pro with M3 Max

When you save your project, the state of all plug-ins is saved as part of the project. Is it possible that the plug-ins in question don’t support the saving and restoration of their state?

Thanks for your reply, Daniel
I don’t know.
In Cubase the plugins save properly.
I’m following some hints from the waves support and forum.
If I find out anything I will post it here.
Best regards,
Stephan
