When trying to change the Buffer Size in Settings under Synplant>Device Settings, synplant 2 stand alone crashes.

Tried uninstalling/reinstalling using the installer and uninstaller, looked on reddit, looked here, and couldn't find anyone with similar issue.

The VST works fine in any DAW but if I try to use the stand alone version of synplant 2 I can't because the buffer size hasn't got a setting -- like, nothing?

The spot where the text should be next to the Buffer Size is blank and can't be altered without the program crashing. (Beachball of death.)

I changed it once and now I can't interact with the Buffer Size setting at all. The buffer size seems to, in the stand alone save its settings in a different file to the VST for that part of the settings.

I've tried looking inside the .app in /Applications/Sonic Charge/Synplant.app but couldn't find a settings file aside from one that's not really user servicable (or not meant to be) so I gave up and came here.

Any help or next steps would be appreciated.
