Patch Request: Kraftwerk - Europe Endless (Bass)

I've tried programming this about 500 times to no avail. I included one of my attempts as an attached filed.

Where I'm struggling:

-The patch in the song sounds like it's filtered & resonant. Trying to replicate the filter just makes the sound too dull, and adding resonance in my synth makes it sound like an acid bass - no good.

-It also has a transient that I attribute to noise; setting the sustain to 0 & the decay fairly fast on the filter envelope was the solution that I found to getting the noise & bass to be plucky. Even then, my patch doesn't have the impact that the original does when it hits the higher notes.

-The lower voice has a 'fatness' to it that makes me think there's chorus or detuned added but I couldn't replicate it nicely.

Annoying issues I've ran into along the way:

-Overtones (particularly the perfect 5th) become accentuated when playing with the pulse width &/or the filtering to where it interferes with the tone of the sound

-The lower voice of the bass patch starts to sound as if it's a semitone or two off due to the pulse width &/or filtering

Any advice on how to proceed? I'd greatly appreciate it!
