The SD2 uses the expression engine components like Rapture, Dim Pro, and many other Cakewalk instruments. All of these ee-based instruments have a "Content Folder" parameter and a "Multisample Folder" parameter which can be manipulated in the Windows registry to modify where they look for their "stuff".
I had already tried that and it failed...but...this time I found out
why it failed. SD3 also has registry entries for the Documentation and Resources folders. (Note that these refer to the actual folders, not the folder that
contains the folders.) This was a herring that made me believe that SD2 worked the same way. I had only relocated the Content folder...and SD2 failed to open. Moving the Documentation and Resources folders to the same place was the "secret sauce" that made it work.
