I know I’m missing something obvious but when I load Slate Digital FGX, I get the old slider based view of the plug-in rather than the more useful graphical view with all the dials etc.
How do I change it from the old ‘legacy’ look to the VST3 look?
In Options / Plugin organization dialog, there is a column “Gen”. If this is activated for a given plugin, this is what you observe. Maybe it has been activated by mistake?
Else, WaveLab can’t open the plugin UI for some reasons, and the generic UI is used instead.
