How to create a scream with a lot of distorted harmonics?

    These two electronic songs have a very similar layering of synths for a few seconds. My ears hear multiple layers but there is one unique patch making a scream with a lot of harmonic distortion. My best description is to call it low distorted harmonics, ramped up to make a the waveform become choppy/unstable. But I've had no luck recreating this.


    The videos snap to start where the sounds are, this is some loud and potentially annoying stuff so watch your volume level.

    The first song is far newer than the second, but I knew I had heard a similar sound somewhere. I know they are far from the same design but I'd love to learn how the root of the sound is created.



    Thanks in advance!

    Well I should have searched...still learning here.

    And for more instability to the harmonics, add saturation and resonance? The most important part being the distortion that flabberbob suggested:

    I'm going to play around with this when I get back from work and post my results. But feedback would be great.
    Cheers to flabberbob as well, you are truly a cool, generous person. :thumbup:

    Thanks, I'm blushing...


    But seriously now, It seems like those are sound bites, cut out of a long tweaking session, much like this demo I made once:

    Just start recording the output of the synth and let it run while you play long notes (a hold pedal or a patch in hold mode using VC's common tab might help) and start tweaking parameters, in your case on top of the filters and distortions the formant and PWM oscillators can also generate noises that sound like chewed up waveforms.
    Hope this helps!
