I think there are several Kontakt users here and I have a Kontakt question I'm hoping someone can help me with!

I own Kontakt 6 and, along with the virtual instruments that come with it, I have purchased several others. And almost all of these instruments load and work quickly.

BUT, some of the Session Guitarist instruments take a long time to load and sometimes they even put Kontakt into that Windows "not responding" mode for a minute or longer.

I guess I should further clarify that the actual loading of the instruments is not the main problem. When I try to preview the built-in patterns that is when it comes to a standstill. For example, when I have loaded Picked Acoustic (or Picked Nylon), turned on the Auto Chords feature, and changed the pattern library, it can take 30 seconds or more for the new library to become available for preview. Obviously this is way too long to wait when trying to preview libraries for consideration.

Any thoughts on what might be wrong or how I might tune this up to improve it?

I have a very fast computer and, as I said, it is only with certain virtual instruments that I have this problem. All Kontakt instruments are located on the same fast hard drive.

Thanks in advance for any advice!
