Next discovery!
Before I open that project in 9.0, I’ve bounced that track to apply all DOP plugins and to save a copy of what I hear and like. Before that I saved all plugin parameters as presets in their preset list. Now I load all presets, but the sound isn’t the same as it was. It sounds completely different.
I will test more. Will post an issue.
EDITED.
There is nothing to post in issues subforum, because my observed situation happens only if 9.5 project opened & saved in 9.0. But, as I said, since we must work with both versions due to hundreds of errors in version 9.5, this makes me careful and the only thing I should ask -
Steinberg’s people, do your best that we can use only one version! Please, please, PLEASE!
