I think in your example also is a comb filter on the bass, which adds those nice, varying harmonics and also that metallic and spatial touch (did not check with headphones though). Renoise’s comb filter is pretty good, you can use that. But I would not use Renoise for the actual bass sound, use a more precise synth/generator. Precise timing, sustain, decay and also curve in the filter envelope is key here for a proper synthwave bass. One oscillator of two (or more) at least could be free running (no phase restart) for a more analog sound. Renoise can’t do that. I have seen that you use ANA 2, just use that. Maybe the second filter also has a comb filter mode? Then find a nice sounding frequency in the comb filter and slightly varying its frequency using an lfo. Maybe even random, but in a controlled, very narrow range. Maybe also sample and hold (s&h) on the lfo.
The comb filter could be also done with a slight flanger. If you add a bit of noise, too, you will add coldness to the sound.
