Quarter Pulse (on Pulse Width middle or 52ish is a Square Wave… when dialing you get a variety of Pulse…) the Quarter is thinner and less buzzy in quality.
For Unison you have 2,3,4 : I advise here to activate Unison with 2 Voices
But and this is very important as this is a Bass : Detune : very little and Spread : very little or none. it’s intended to boost the sound.
Quarter pulse I would say it’s more than -32 (it’s thinner than that)
yeah the filter cutoff envelope is just a little so you guess good with depth 8.
Also you have to find the right mixing level (oscillators a level + oscillators B level) between the Quarter Pulse and the Triangle (sine)
When you ask for pushing back in the mix the bass sound, if you listen your references, we hear the Bass it inject the groove, we “not” feel it (at least in the sub register) we hear it… it’s kinda acoustic by design (or nature) the kick provide the subs… to a certain extend if I can say that like that so you understand (that why I said the bass is not subby or very loud that doesn’t mean the subwoofer in club will not make the groove even better) that’s also why the the pulse and the triangle sit to the same octave as pairing.
it’s level in terms of balancing (probably a bit lower but it depends on the main element) and EQ to shape the bass frequencies (and it depend about you bass sound, you kick and the other elements)
another thing we are all guilty of that, most of us start with the Kick, some drums elements and the bass… we try to find a pleasing part, mixing, processing… nothing wrong with that ! but often we do too much mix and process already and the spectrum is already eaten 
BUT
You should equally port attention on the low-end couple as well as the higher stuff in frequencies. especially because it’s the whole that giving the overall groove and sonic characteristics. If you don’t add the higher part I would not shape my bass extensively sound too soon (sure you have to find or design something that you like and work in context)
from what I heard from your references, “I” would focus on the keyboards first (we clearly have those in mind and it’s the main element) and the full beat and then your bass groove… complimentary to the keyboards + mixing & processing
(to me) it’s easiest to get my music theory harmony (what key my song is) what are my melody or chord progression. Part of my groove is my beat elements already in place (usually it missed some stuff or you have too much) and then I play my Bass and enrich the keyboard by providing the bass part and its groove. it’s just a personal advise on how I feel and prefer in this kind of track to work in terms of order that I find easier to work.
To summarize :
(it’s my personal thinking on that some may not work like me) I usually need a kickstarter in my own creative journey, whatever this is it could be anything and even sometimes I challenge me by changing completely my entry point. But I have to find my leading Part that’s where it’s kinda tricky sometimes it’s the Bass that leading my project sometimes it’s not. Sometimes the music genre gives me a hint on how to approach that as well. (if I know that early in the process)
I don’t mix, process (extensively) until I get the leading part. Not because I anchor on that part, but because it’s what I want to eat the space, it’s my point of focus. Then everything that comes against or compliment that point of focus will need to be shape/process to occupy the spectrum… and sound choosing to that part have a bit role even before to mix/process.
From your reference track the Bass are not leading the Track it’s the Keyboards. and so, I would possibly set a counterpoint with a simple sub so I can shape my beats & groove start… I can also start to feel a movement to groove until I get my keyboards right… that way it will be easier for me to find the right Bass for the right keyboards (or leading part) and even design the bass in context, then mix/process to the other parts.
It will also be easier to find the right complimentary bass groove for the leading part groove… could be call & response, could be enrich the overall groove, could be counterpoint, etc… could be bass reinforcement… it will help me also to play the bass with the right timing in terms of note decaying in relationship with the keyboards on how they last… (like lazzy on keys, fast on bass, opposite or similar for both)
Seriously though, it means a lot that you’re taking time to share insights and help others gain knowledge.
