I haven't been making any music lately so I decided to sound design with Massive. What I've found out is that White noise can be used for a Dubstep growl... like the stuff in transformers if automated and filtered properly.
Have a listen.

And the patch if anypony wants it... Note that this patch is played 2 octaves below C0... don't know about other DAWs but I used Ableton to play it.

Also... Inb4 White noise is an oscillator on some synths.
