Full Kontakt is worth having JUST for the free Libraries you can get
like the Sonokinetic ones, and a plethora of others...and you can get
it cheap by getting the Seinnheiser FREE drums, and then crossrading
to it! I don't know why any serious music maker wouldn't have it. It's
a staple of music production just about everywhere. Granted you can do
fine without it, but you can do a lot better with it IMO!
