All Kontakt Patches available on MultiTracks.com require Kontakt 5. They will not work with the Free Kontakt Player.
Copy the Patches folder you downloaded and it’s contents to any location on your hard drive. Then open Kontakt 5 and find the folder you just copied under the ‘Files’ tab in the top left hand corner. Locate and open the files .nki and .nkm files located in the ‘Instruments’ and ‘Multis’ folders to open the presets.
If Kontakt brings up a ‘Samples Missing’ pop-up window, simply click on the ‘Search Spotlight’ button to locate samples or the ‘Browse for folder’ button and choose the ‘Samples’ folder that contains these samples in the location you installed them.
