Once inside Kontakt, you simply navigate to the sample’s location using the Files tab, and double-click the ‘.nki’ file (indicated by a little piano keys icon).
It does not matter where your sample libraries are kept, but we recommend keeping a tidy folder structure of either instrument categories, or developer name.
NOTE: If your version of Kontakt says “KONTAKT Player” in the top left corner, then you do not have the full version of Kontakt. That is the free version, and our products are not compatible with that.
