KH Chamber Strings is now shipping in both Gigastudio and Kontakt 2 formats.
Sorry that the Giga version took so long. I've been working hard on that, and also working on really nifty legato and glissando scripts which shall eventually be implemented in the Kontakt 2 version of both KHCS and KHSO.
If you happen to go to NAMM, I will be showing the libraries there. Email me at MuzkGuy@aol.com for more information.
