Pretty sure there are software emulations made by TAL of both but I can't vouch for the quality.
They are terrible, imo.
To me it sounded like a filtered square, there's a tiny bit of growl in the sub bass, could be the limiter, could be that it's square.
Otherwise, try a sine wave slightly slightly modulated by a triangle in a FM synth, same ratio.
Chorus is just going to diffuse the strength of sub bass, try using a limiter instead, that will re-enforce it. I see you have camel phat, that can be decent on bass, try it before and after the limiter and you will get that sound soon enough.
