I just wanted to convey my thanks and appreciation to Dean with Cakewalk support for helping me resolve the issues I was having with Rapture Pro. He really came through in a big way. BIG THANKS Dean. Your help and support is/was greatly appreciated. 

What was the problem and the fix?

You're very welcome! Please let me know if there is anything else.
 
BobF, the problem was that some of our content packs (orchestral ones in particular) rely on some of the content in the Legacy packs. Some patches will be silent if the legacy packs are not installed. Since the legacy packs are the same as the Dimension Pro library, people haven't installed them to avoid having duplicate content. To make sure all his patches are audible, I sent individual audio files to him.
 
This will be addressed in a content update that will be released in the near future.
