I found this excellent tutorial over on dubstepforum.com for carving oscillators out of white noise with Massive.

Original post by Chewie

This is a technique i learnt from using zebra so props to Urs Heckman for this. I thought i’d try it out in Massive and got some interesting results – like gnarly evil bass oscillators

Right start off with an initial patch in massive
Turn off the oscillator 1 – we don’t need that we’re going to create our own.
Turn up the amp of the white noise a little bit like this:

Next have 2 comb filters running in series with the damp and feedback parameters at maximum.
Turn down the main volume so you don’t blow your speakers:

Right now we stick the feedback to full at the bottom left:

Now we’re going to tune the oscillator by changing the pitch of comb 1.
I’ve put it to around the 9 o’clock position but feel free to get the tuner out in your daw and get it tuned to what you want.

Next we move comb 2′s pitch higher which will create a nice phased/comb/flanged effect as you change the pitch up and down:

Now we need to set up the feedback loop so it is going back into the filter circuit at comb 1 like this:

Now it should start sounding pretty gnarly at this point. I’m now going to add some movement to the sound by sticking an lfo at 1/8ths sine wave on the damp parameter of both comb filters:

Now i’m going to change the rhythm of the lfo by having it sidechained by another lfo. So here i have set the lfo 5 to 1/16 ( from 1/8th) and placed lfo 6 in the SC mod box in both comb 1 and 2′s damp. I have set the lfo 6 to 1/2 as a sine wave also. To activate sidechaining i have clicked SC underneath the 6 and the down arrow below 5 like so:

And last thing is to beef up the sound by going into the voices tab and setting unisono to 3, switch on pitch cutoff and move slider slightly across ( not too much):

Now just experiment by routing the feedback to different positions to get different noises, add a simple delay to the feedback loop with a minimal seting to basically create another comb filter etc etc
