FYI: Works correctly standalone!
Win 7 Pro SP1, 64-bit, 8GB, Dual Core
SONAR 8 Producer 64-bit
Just purchased, downloaded, installed Oberheim SEM V 1.1. Standalone, everything is great. Using 64-bit VST hosted by SONAR 8, I can't change patches. The UI shows the patch change, but the initially loaded patch persists. That patch does sound, but won't change.
Thanks for your help.
