Any clues how to create this bass sound?

Seems like metal bands are going for the wobble bass as well...? There are many tutorials and suggestions in this forum for that kind of sound, just search "wobble", "growl", "talking bass" etc. Although IIRC you are using a Virus C which has less options for oscillator types and distortion characters but this is the general idea:

In this specific sound it seems like the LFO controlling the wobble randomizes its rate on every new note.
