Don't want to be "that guy", but installing Golden Gate might indeed be part of the problem. It's a golden rule in audio to never ever install a new operating system until it is made clear by every developer (if possible) that it is supported.thanks, wonder if it's because I am on Golden Gate OS...
If i create a new track and load a synchron preset and look at my sound variations map I don't see any options to edit the map, there should be a "new variation" and "remove" button to make custom maps, right?
Also, if i then load an empty map I saved before and save the instrument preset and then load that preset on a new track it again strips the custom "empty" map and auto-loads the sound variations from the current synchron preset.
It could be the problem is not Studio Pro but the library you are using or a VST3 problem that surfaces on Golden Gate.
On the other hand, you are in touch with support, so they will probably sort you out. But still: try to always wait at least 6 months until you upgrade your OS:
