1: Uncompress the downloaded .rar file in your favourite Sample Libraries folder.
2: Kontakt patches are stored in the "Instruments" folder.
NOTE: Please, remember to keep both files and folder structures or Kontakt will trigger a pop-up error message asking for missing files. In that case, all samples are stored in the Samples folder.
You need FULL version of Kontakt 5.1 or higher in order to properly load this library. Kontakt Player is not supported.
