I think the only way to be sure is try a demo version first. They
should work using the VST-adapter, but as there is this "outsider", the adapter, in the picture, it's quite possible that everything doesn't work quite flawlessly.
IIRC I bought Addictive Drums when I was on SONAR PE4, the last version that needed the VST-adapter, and then I could not get all the kitpieces/outputs of AD to separate audio tracks, because there was some limitation on SONARs side.
