If you bought Kontakt from Native Instruments (or a different vendor), you are most certainly using the full version of Kontakt. If you downloaded Kontakt for free from the Native Instruments website or as a part of the free Komplete Start bundle, then you are using the free Kontakt Player plugin. It comes in two versions: KONTAKT 6 PLAYER (free) and KONTAKT 6 (€399). Kontakt is the flagship sampler plugin by Native Instruments. Sometimes you will see a “demo mode” message even though both the Kontakt Library and Kontakt Player itself are free. Indeed, using the free Kontakt Player by Native Instruments can cause some confusion, especially if you pair it with free libraries. One of the most frequently asked questions we get is a deceivingly simple one: “Why is my Kontakt library working in demo mode if it’s free?”
