Thank you LBH.
I love manuals, but obviously, I didn't go deep enough here. It's also not obvious what the original samples are unless you want to correlate the 'date modified'. I know that's not a huge leap in logic (if it was modified in 1983, it's probably an original sample), but to my mind, it's lazy, or sloppy, or both on Arturia's part (just like me when I didn't catch/ignored the information in the manual at 5.6 - guilty as charged, facepalm, no excuse, etc.).
I appreciate the help very much and by the way, for whatever reason, still crickets from Arturia.
Cheers - Jerry
