in the mixer window of kontakt there are faders and above that are slots for inserts, simply add an eq insert. if you load certain snares there is a limiter on the track by default, thats where you can load inserts. the mixer view should be a tab at the top of the whole instrument with what looks like 3 little meters in it.
Thanks! Finally found it. I was looking here, but apparently the window for slate was kinda being cut off on my screen, and it's the very bottom effect when you click on the insert tabs. Any way to fix the size of the window of a plug in?
