I also have a CS6000, so went to check on the pak of needles that came with it. I don't see anything that says "organ" on the pak, but here's the printing, just in case it helps.
EINFACHE NADEL...3STK
Hope that makes sense to you - sure doesn't to me.
Wait a minute - I just opened the pak to make sure it was a regular machine needle and the foil wrap around the needle does say Organ. And it is a regular machine needle, not the double needle.
