Thanks William
 
I'm probably being really stupid here but how do I set up a track template in Sonar so it loads one instance of Kontakt with say 12 articulations of LA Strings and a separate midi channel and track for each that addresses the one instance of kontakt?

Robert said it really well, see that other thread.   http://forum.cakewalk.com/Kontakt-One-big-instance-or-a-separate-instance-for-each-instrument-m2253267.aspx  You have to wade through a variety of comments ...  (edit) Oops I think I referenced this thread from within this thread ... well, read it all, good comments here and there.
 

Thanks I think I've find Bob's thread you meant care of DR Google:

Thanks very much for your help, a major penny has just dropped, now if cake would just implement folders within folders so I could have all my various string libraries and associated articulations held in a master Strings folder then my world would truly be rocking!
