In the comments of that youtube video above, the guy shows how he got there. I gave it a try, and while it's not perfect, it certainly got closer than any synth/preset I've tried besides the one in Arturia.
So according to that guy's recipe, basically you put both Osc's to saw, set the lowpass completely open, no or very little hi-pass. I turned the sub-osc off, fine-tuned the second saw sharp by just a hair (you'll start to hear the phasing if you start from 0 and move slowly). Set the amplitude attack to 0, decay to 0, sustain to max, release to 10'oclock or so. Turn off LFO. Add some slop. I added some chorus, and you can tweak reverb/delay either on the P6 or your rig, to taste.
I couldn't get the glide working for me, but it's definitely there in the song except for the intro.
Also, while I was listening for the glide I noticed like a ghost track of Dave's vocals around :11 that I never heard before. Right after the scream, there's like a little barely audible snippet of something in the vox. Cool, prob just someone's headphone mix bleeding in.
Anyways, I'd love to see if someone who knows wtf they're doing can tweak it from there and get it sounding tight. Oh, also I guess it goes without saying that you can't really play it on the P6 keyboard...not enough keys. I just used my 88key controller.
