Hello. Maybe somebody had the same problem? I use VPS Philta, and when save the project in Sonar, after opening it I have to set the settings anew. In FL Studio it is ok. Sonar X3e Producer.

I've had the same issue. What I used as a workaround was to save the settings as a preset in philta and recall them when i reopen the project. It's not a favorite plugin though so it really doesn't affect me that much.
I believe I submitted a problem report for it a while back but you might want to as well.

Thanks, so it must be how it is. I also do the presets. Then will use other philter or EQ.
