Also think there's definitely noise added into the mix. The noise will only sound like that with the right kind of distortion and filter, I think it's probably a good idea to use the "analogue" filters, to get that squelchy vocal thing out of the resonance, like said above... So that leaves us with distortion for the fx section, try them on! There's also some filter movement going on, give it some env amount and adjust the filter's envelope with some attack and some decay (try those settings). It's also good idea, probably, to modulate the amount of distortion with the same envelope, so as to reinforce the movement. If it still sounds off, which it probably will, I remember doing a patch in which I add the mod wheel opening the cuttoff, while bringing the resonance slightly down, the noise volume up, and the reverb amount up to - of course this can all be done using envelopes as well, but gives you less control (even though you have some more now with OS 5, right?)...
The Oscillator section, could be a couple of sawtooth (or rich sounding waves) detuned from each other (in sync?), make the patch mono and add some unisson at the end, with a touch of detune and spread... I think with a little tweaking you'll get there and probably to a lot more sounds on your way
