This might sound a silly question, but it's not clear from the manual.

I have GS3 Orchestral and use Cubase. Now, I can get the instruments sounding in Cubase, but not the Gigapulse. Where am I going wrong? Also I would like to know if you can use this version of Gigapulse as a separate plugin FX in Cubase to allow it to work on non-giga instruments?
