I discovered what happens. Since we are pressed to use both versions (9.5 and 9.0), the project I mentioned in previous post created in 9.5 I opened in 9.0 and then saved after some changes. Then opened in 9.5 and all parameters in DOP are default. So this creates new question - if project file is so complex allowing to store DOP list and parameters of all plugins attached and previous version of Cubase don’t change the DOP list it self, then why it removes parameters of plugins in that list?
This happens only on Plugins, not Processes (Fade In/Out, Envelope etc.)
I’m programmer and I don’t understand this.
