[sdiy] New schematics

[houshu at muj.biglobe.ne.jp]

Hello List,

I updated my site with several new schematics.

  http://www5b.biglobe.ne.jp/~houshu/synth/index.html

Most of the new schematics are not built yet.  However, I'm sure I 
can't take time and space to test them myself for a while.
I thought some of my ideas could be inspiring for some of the list 
members.  So, I decided to publish them.

* Variable slope-ratio triangular/sawteeth waveshaper (AKA Tillman's modulator)

* VCFs

 - Simpler design of totem pole VCF:

 - Biquad filter with Steiner-VCF-style function:

 - Moog style HPF (Heavily modified for my taste) :

 - New style filter (with smooth asymmetrical distortion) :

* VCA

 - A method to increase the input dynamic range:

* EGs

 - Output buffers have been changed.
