>>is not a chaos module a white noise generator..? or are we talking
more
fractal type stuff here..?

More along the lines of fractals. But leaving it at that would be
misleading.



>>how's about chaining a pile of 100s & 101s together..?

People commonly use the term "Chaos" to mean "random," but it is not at
all. I like the "Dark Star Chaos" module a lot, but its use of the term
is more in line with the common understanding of Chaos than any true
'academic' use of the term.

No, white noise, and lots of 101s, are still "random." Chaos may sound
random at first to the untrained eye/ear (?), but it isn't. If you let a
chaos oscillator run, for a short while what it produces sounds random,
but as it runs, its output begins to show itself as being structured in
a "not quite predictable" way. Perhaps you've seen "strange attrtactors"
diagrams (erroneously called 'chaos butterfly graphs')? Imagine an LFO
like that, with two outputs that define two intersecting planes of a 3D
strange attractor space? I stay awake nights imagining what this might
be like, what kind of "Forbidden Planet" sounds I could make with a
thing like that.

I have heard some very awful and some very beautiful music/sounds using
Chua Chaos Oscillators ("Chaoscillators"?). Some of the eeriest, most
"alive" vocal and oboe-like sounds you've ever heard. It requires a lot
of tweaking, of course. There isn't a "sweet sound" output. You have to
"find" these sounds amidst the chaos.

Someday I am going to have the time to make one of these puppies. The
basic circuitry is astoundingly simple. Just need to add some
intelligent, useful VC stuff to it.
