Vocodex and the AI wavetable

How do you think they made the main bass in that? To me it sounds like it's 2 layered synths.

How would I go about making these bass sounds?

I found this patch and I really like it. I just plopped a Sausage Fattener, Limiter, and other shit. Kinda talky kinda growly. There is also a pitch envelope but it doesn't make too much of a difference. Play around with it.

Ok so I was wondering how to get nice growls from FM synthesis. I can make alright leads, guitars but not growls and that is what I really love in the music. For example Knife Party or Excision make amazing sounds from FM.
