Just did a quick test… New project… added a kick drum to an audio channel with Ozone and L3 Multimaximiser, routed through a group, also with L3 and Ozone and then an additional L3 and Ozone on the Stereo Out, so that’s a chain of 6 plugins. Bounce the session and the result is perfectly in time.
That’s not what I expected because from memory I did some tests a long time ago and found that Ozone and L3 caused things to be delayed. Maybe it only happens under certain circumstances e.g. in a very busy project. I’m not sure, but seems like it would need further testing to find out exactly what’s going on here.
