[sdiy] SNICster demo up

[Ian Fritz]

Hi All --

I've put up three demo files of my new waveshaper, in its current state of 
development. You can find them here:

http://home.earthlink.net/~ijfritz/xfer.htm

To make these I set up a bank of LFOs to sweep through two random sets of 
control voltages. One voltage controls the shape (saw-> tri) and the other 
controls an admixture of the input wave with the shaped one, using either 
addition or subtraction.

The first file uses stepped voltages and has four sections demonstrating 
the combinations of tri/saw driving input and the two summing polarities.

The second and third files are experiments with audio-frequency timbre 
modulation and the use of the shaper in conjunction with a VCF.  Both 
stepped and swept LFO modulation are used for these.

I hope these give some idea of what the unit will do.

And the name?  SNIC = Saturating Negative Impedance Converter. If that's 
not nerdy enough, I don't know what is.
