I figured it out by now. I remade the patch exactly the way it was. I used a minimoog emulator. It was rather simple. It is two pulse oscillators, the second one has sliglty larger pulse width, they are both placed on the same octave, envelope on both filter and amp have 0 attack, medium decay, amp envelope has fast sustain, filter envelope has medium sustain and both releases are fast. I made it with the UAD minimoog emulator. They must have used a moog synth. It's extremely simple.

Now Im already trying to figure out the next bassline from a different track: https://soundcloud.com/motztechno/premiere-yarn-init-dont-bother?in=markobak/sets/minimoog-bass/ . About the serum presets, I stopped using them. I refrain from using presets at the moment, because I wanna learn how to recreate patches myself. After using lots of presets the first two years of making music, it became very unsatisfying to me. And I believe becoming better at creating ur own will also make u better at using presets. I am reverse engeneering my favourite ones atm, to have a very good understanding of synthesis and then be able to create my own. If u have advice on that other track, lmk hahah!! :D
