Since the subject has come up...

Is it possible to create a digital noise module with a rotary switch (or VC
morphing) between different "kinds" of digital noise?

White noise is a "pure concept," and Pink a filtering of that... Digital
noise modules tend to be registers filled with random seed values, and by
giving VC of the clocking rate, you can get some weird effects.

But I'm wondering if maybe there could be some other mathematical functions
that could seed those registers with different probability spreads. I'm not
sure exactly what I'm saying or what it would sound like, but it seems to me

that there are lots of different degreees of "randomness" in the world, and
these could produce different sounds.

I would imagine that some weird non-ring-modulator metallic sounds could be
produced this way. Maybe a control for how many "peaks" in the spectrum,
another for how spaced out they are, and another for "tuning" those peaks.
Almost like pre-multi-bandpass-filtering white noise, but really it's done
mathematically (i.e., not with an analog bandpass filters) and then seeded
into the playback registers. Then a fourth control could modify the clocking

frequency and a fifth would be an attenuator for incoming voltage control of

the clock. Or maybe VC of some of the other controls too. Four initial
controls and four complimentary attenuators.

I dunno...just waxing poetic. I think there is great wealth in non-harmonic
sounds, and producing these is an inherent weakness in analog synthesizers
(usually you can only get it by filtering white noise, using a ring
modulator, or a helluva lotta sine wave VCOs tuned all 'funny'). So I like
to attack that weakness when thinking of "new" modules. (Still want that
Frequency Shifter.)

I'm looking for a way to produce the sounds of metal, wood, rubber, sizzling

bacon, bacon being rubbed on metal, the wind on Beta Epsilon Eridani... you
know.

I still think that a "true" (i.e., 'academic') chaos module has merit.



Anyway, my 2 cents.
