A word of warning:
KH Lyric Series String Quintet does not work in Kontakt 8. It does work in Kontakt 7.
Both the Virtuoso Ensembles and Spotlight Strings do work in Kontakt 8, at least for now.
I am using the latest 3.4 GHz, 64 bit version Windows 10 with 32 gigs of ram, thus my system is not the problem.
So if you have Kontakt 8 you may want to try the demos prior to purchasing.
YMMV


I'm no longer allowed to go caroling at the psych hospital.
I guess Do You Hear What I Hear was a bad song choice!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
