Anyone have any good tips or references to how to make these types of sounds/basslines?  Maybe any sound design videos that are in a similar style.  I was also wondering if you think Fatum may be using sampled bass sounds as well?  My current approach to these types of sounds has been with Serum.  I have been using saw waves mostly.  and then for processing I have been using saturation (camel crusher/decapitator), Ableton's redux, and some other processing, maybe compression.  Also I have tried some of the formant filters modulated with an lfo for some interesting effect.  I understand that these sounds have multiple layers but does anyone have any tips for these sounds? Hope everyone is doing well.
 
Cheers!
