[sdiy] chaos update

[Ian Fritz]

Hi Folks --

I have made some more progress in my development of chaos generators for 
use with analog synths.  The current system uses a slightly different 
topology from the first one that I previously posted, and it has a wider 
range of nonlinear functions.  With two comparitor nonlinearities, the 
circuit can make a quadruple scroll (compare the double scroll of the 
Lorentz system).  The system has a total of about 20 controls at this 
point, including a bunch of 12-position switches to set the parameters of 
the system.  Using switches is the only way I feel I can get reproducible 
settings.  The system has voltage control of frequency, loop gain and loop 
offset, the latter two of which  give voltage-controlled bifurcation.

Some new demo material is up at this web page:
