BrorGaben:For example the 1:31 and 3:24 fx kicks or just any fx kick in the track.
What I do most of the times is this.
I eq out all the frequencies I don't want. Also I boost the frequencies that I want to filter in order to get the fx kick. Most of the times that's between 300 - 1100 hz. After you have done that you probably have a very harsh sound.
For the filtering, I like to use Camelphat3. I think the "Lowpass Fat" filter on it works very well for this. First off, clear your preset so you have nothing else going on in your Camelphat. After that, enable the filter section. Put the resonance between 50 and 75%. Open up the Envelope and the Cutoff. You can play with the envelope and cutoff the create the sound you wish. From my experience I call tell you that automating one or both these knobs will create the best sound. In my opinion of course. Another thing that you can do is add some distortion from Camelphat. It can give your fx kick more power.
If you don't have Camelphat, no worries. You can do this with pretty much every filter plugin. Or even with another equalizer. I just think this is the easiest and best way. Hope you undestand it now.
