Bought some 3rd party kits (Yurt). Following the import instructions, some of them (2/3rds) end up in my library.
Of the kits that do not get added to the library (Indie Rock Battery Bundle):
I can load them by navigating to them via the files navigator, and they load just fine:
Notice that I've got the path to the Indie Rock Battery Bundle in the preferences:
But the kit I loaded (Spork Kit) isn't in the library list:
I've tried renaming the files and folders, but can't make it work.
Notice that I have these on a drive dedicated to my 3rd party content (including all the Native Instruments content), as opposed to the default location (ie, C:\Users\scott\Documents\Native Instruments\Battery 4\Kits).
Also notice that these are not in the same folder as the other Native Instruments content.
Lastly, notice that some of the other Yurt kits (Drumkit Bundle, EFX Bundle, etc.) actually do get imported in the library.
This is on the Windows 11 OS.
