You should be able to use them with the VST Bridge. I’m not sure how it works on the PC, but on the Mac the Bridge is a piece of junk. In order to edit any parameter you need to:
- Stop Cubase playing (or go to step 2 and Cubase automatically stops).
- Double-click on the plug-ins mini-interface.
- Make your edit
- “close” the plug-ins full interface
- Start Cubase playing
If your not satisfied with your edit, you need to go through the entire procedure again.
This is too unwieldy to be of any use, in the long run. My advice is; Upgrade those plug-ins that are available in 64-bit and throw away the rest (this is what I have done). This is true for effects as well as instruments.
Or you could run Cubase in 32-bit mode and everything will be business as usual.
