[sdiy] VCCO demos/schematic

[Ian Fritz]

Hey folks --

I've put up a schematic of a VC Chaotic Oscillator and some sound clips on 
a web page (below the scope shots put up before):
http://home.earthlink.net/~ijfritz/xfer.htm

In the first demo, the system is moving slowly around its attractor and the 
chaos is quite strong.  The output variable x is controlling a VCO's pitch, 
x' is controlling a filter frequency and x'' is controlling the depth of 
some AM "growl".  The more rapidly the system is moving, the stronger the 
filter sweep and growl.

The second demo combines some sounds with a more rapid rhythmic motion.

The last two clips use two variables to modify the sound while the third 
variable fires trigger pulses generated from a fixed threshold.  So it 
seems useful to use both chaotic event timing as well as chaotic control 
voltages.

Thanks for listening!

   Ian
