If you have an S Series Native Instruments Keyboard, you can take advantage of the NKS functionality in all Sonokinetic products, which integrates with Komplete Kontrol, the S series keyboard and Maschine.
Make sure you download the latest version of your Sonokinetic product using the Sonokinetic Manager and add it to Kontakt using Native Access.
The product should now be available for use in Komplete Kontrol.
If it is not, make sure you update both Kontakt and Komplete Kontrol to the latest version using Native Access and try again.
If it still doesn't appear please open a support ticket.
P.S. Legacy products (so products that are no longer sold in our store) are not NKS compatible
