Looked inside one of the new massive X expansions from the “library”, but it’s got a .nicnt and I only know there’s a way to add that kind of library to Kontakt, can this same method add an expansion to massive X? Or does it have its own add library button? Just wondering in case it’s possible to manually add new expansion packs to massive and have one tool for both library requires…

 

Make a new folder and add to: C:\Program Files\Common Files\Native Instruments. For example "Now" folder. Make sure the "PAResources" folder is a subfolder in the "Now" folder. Open the registry and go to HKey_Local_Machine. Go to "Software" then look for "Native Instruments". Right click on "Native Instruments". Select "New Key" and name folder "Now" and add the ContentDir and ContentVersion as strings. Make sure the directory is linked to "Now Library" - C:\Users\Public\Documents\Now Library.
