I've tried the instructions: click below my first instrument, back to Library, select my second instrument — it just replaces the first. Likewise with dragging/dropping.
I've also tried File | Options | Loading: uncheck '… replaces currently selected instrument."
I've also tried File | Options | Handling | Midi Channel Assignment now set to "next available".
No matter what I do, any additional instrument I try to load just replaces my one existing instrument.
(I have the full version.)
Thanks!
UPDATE: So, I'm upgrading to Kontakt 8. I need to keep Kontakt up to date anyway. The only feature I'm looking for is the ability to add a second instrument to an instance. :-)
HELLS BELLS: I'm having the same problem with Kontakt 8. Why is this so hard?
