Audio Zombie has released a collection of free synth patches for both Kontakt and EXS24:

AZ SimpleSynths is a collection of synth instruments for both Kontakt and Exs24 software samplers. This collection offers a number of typical synth instruments for electronic music
production.

I used Es2 synth for sound design here and modulation for each sound has been
made with Es2. So i made no use of samplers filters or fx all you get here are synth
instruments sampled from Es2 synth which i programmed. Of course you can make
use of samplers filters or fx’s if you want to or when it’s needed.

You can preview the patches above. They are available as a free download from the AZ blog.
