Version 5.5.2 introduced deeper integration with Native Instruments’ hardware ecosystem (Komplete Kontrol and Maschine). It implemented the Native Control Protocol, allowing the software to interface visually and tactilely with hardware screens and knobs.

Upgrade pricing from Kontakt 5 to Kontakt 7 is typically $149 during seasonal sales.
