Realitone were showing their just released Nightfall - an enhanced string library which takes elements of their Sunset String Library which used top L.A. session players at the renowned Studio at United Recording in Hollywood. They started by using elements that were not included in those original sessions adding additional processing and expression possibilities for a more Hybrid String library.
It requires Kontakt 6.2.1 or higher (pre-release version) but will work in the Kontakt player when it has been officially released - free upgrade. There's also a bundle for both Sunset Strings and Midnight Stings.
They put it in words only they could have written ;-)
