MAJORITY OF THE PLAY SERIES ITEMS HAVE BEEN UPGRADED TO ONLY FUNCTION IN KP 7.6 and up. Unfortunately you will get an Error message saying your version of Kontakt Player 7 is too old. I recently found out the hard way even with Duets play series which said that it could work in Kontakt Player 7.1...so I purchased it and boom the error message. NOTE the EXPANSION PACKS are cool so download away because they don't need KP7 to work. Unfortunatley I can't Update my Mac OS past Catalina because of non Apple ssd and firmware error message lol anycase Buyers Beware of the Play series because it will NOT work unless NI Decides to make a downgrade link specifically for your product here >>>>>> https://community.native-instruments.com/discussion/17039/previous-versions-of-recently-updated-kontakt-libraries-compatibility-with-k6-older-libraries/p1
