Hmmm. I think with SONAR 3, I started with "Producer" and then went to "Producer Expanded" whenever they introduced that, but somewhere along the way (maybe X1? or X3?), I decided that I didn't need "everything" and went to plain SONAR and SONAR STUDIO. If I recall correctly, some of the Producer and Producer Expanded versions of plug-ins worked in the less-than-Producer versions, but some didn't. Maybe that was when I started my Spreadsheet.
I do remember getting messages like "not licensed for ________" with some plug-ins (i.e., some plug-ins could only be used in earlier versions). I am just starting to get back into doing music (or trying to start). So, armed with your spreadsheet, I can now revisit all my plug-ins.
Thanks, too, for the link to the Documentation page!
