Am I right in thinking that if one owns Rapture Pro these will only show up in Rapture Pro and not Rapture x64?
 
If that is the case is it possible to get them to appear in Rapture x64?

It is a mix. The samples are installed with the Rapture samples, the programs are installed with RPro. If you want to run the programs in the original Rapture copy the "Kick Start" folder from the RPro Programs folder (the default is "C:\Cakewalk Content\Rapture Pro\Programs" into "C:\ProgramData\Cakewalk\Rapture\Programs" and refresh the Rapture browser with F5.

Thanks Scook

Personally, I think it sounds better in Rapture Pro...could be my imagination, I guess.
