Looking for an bassline effect

[BLoodstaiN`]

In the following songs there are both synths that go like:
uuuuaaaaaa, if you would shape your mouth like that
i think it's something to do with the lfo but how do you do it, i've been searching for it for a long time, and the only possibility i have yet found is, An LFO on the Intensity knob in MASSIVE.
if i do that, i get a small effect like that, but not the uuuaaa i'm looking for.

Shock one - Crucify me

Ganja white night - i smile when i kill (At the end in the dnb part)

I'm really searching for this effect because i got some heavy basslines i want to apply it too.

If anyone knows, please leave a comment

This is a tutorial explaining how to make the "yoi" bass you usually here in dubstep. But it generally explains how to get the effect you are looking for. You just need to slow down the lfo

Already have checked that, but then you're saying i need to use other synths to get the uuaaa?

 

[Mr Fletch]

huh? No other synths needed.

Follow the tut, and note when he adds the lfo to the intensity of osc 1, thats what creates the yoi effect. Which is essentially what you are trying to make, but a slower variation of it, hance why I said you would need to have a slower rate on the lfo...

Alternatively, instead of adding an lfo to the intensity knob, try adding a filter with a slow attack and quick release

Formant filters, bitcrushers etc can all get you a sound similar to the one in the shock one tune. Using envelope filters to shape the sound works best for me rather than lfo's but i'm sure that there are a million ways to get there

There's also a tutorial on youtube of skrillex bassline. There's one thing i could use, i learned a automation on your waveform can also give you sometimes a roar or whuuaauw effect.
