It's four parts and kinda wordy at times but it does a good job explaining it from a conceptual point of view for someone who's new to compression. Obviously if you already know your stuff this isn't all that useful but it's still an oldie but a goodie.

So I was dicking around and making a bass in Synthmaster (not a whole lot of people use it) and I think one of the tricks to getting that sorta "wruahh" tone is to have the modulator you're FMing with (Massive's Phase OSC is essentially just an Sine Wave FM oscilating whatever wavetable you select) set two octaves below the courier. In the above example I quickly farted out, the 1st has has the modulator at the same octave as the courier, the 2nd with the modulator -12st (1 octave) below, and the third with the modulator -24st (2 octaves) below. (I know this example still isn't really the kind of tone you're trying to get at but I think it's a matter of choosing another wavetable)

You could try setting your first oscillator -24, +12, +24 or pretty much any other octave interval and playing the MIDI at different octaves to see if you get any closer to that "wruahh"

This was something I made ages ago on the Dubstepfourm Growl Bass thread and it has a kind of similar tone to it I guess (I was going for a Kill The Noise style sound but it's somewhat similar to the example you mentioned.)

I don't actually have Massive installed right now but I'll just throw a bunch of batches at random that I made that have a similar sound based on what I remember, though I'm pretty sure either "Kill The Noise Growl" or "Growl Patch" is the one that used just M-Talk I made on that DSF thread

(shameless selfpromotion) I've got a similar sounding bass in one of my own tracks that I got by running 7 unison-ed saw waves (using TyrellN6, a freebie u-he put out) into one of LePou's free (and very high quality) guitar amp sims with some eq after to taste (so no cab-sim.) I used LeCto but I'd recommend you dick around with the different amps to get other tones. I know the mixing's not the greatest on this put at about 1:40 is when the bass I'm talking about kick's in (in retrospect I probably should've kept more of the mid-range in there, hell OTT probbaly could've done a good job of that)

Frankly a lot of the more traditionally reesey sounding bass lines (think late 90s-early 2000s jumpup/breakcore, not your more modern Noisia/Skrillex/Feed Me growly processed stuff) can be summed up as "Saw Waves -> Effects like filters, EQs, phasers/flangers, whatver -> Distortion -> More filters and shit -> OTT & final EQ" so really getting different textures is more a matter of how you're going about your FX and distortion than anything else.
