Background: I quite often click the wrench and go "under the hood" to tweak settings in a library for a particular piece of music. This can include things like increasing the volume of a particular zone, adding pitch bend, changing entire groups to TM Pro, etc. I do this to protected as well as unprotected libraries. As I work within Plogue Bidule, I simply save the entire Bidule layout and it all comes back, tweaks and all. I DO NOT save any of these tweaks to the actual library. As a result of this, I haven't been updated these libraries out of fear that they won't reload in my Bidule layouts. But, I now find that I would like to update some of them. My problem is that I don't understand what the pitfalls are here. If I save my tweaks as Snapshots, will they capture these "under the hood" changes? If I save them as nki files will they load into the updated library? Can anyone explain how this works? I have looked through the Kontakt manual, but it isn't detailed enough. I've tried to search this forum, but its a tough thing to search on.
