VC Waveshaper from the test bench

     I'll get it up on a web page somehow... fax machine humming...

<snip very cool waveshaper idea>
     
So, as you raise the CV, the ladder causes each threshold to go up 
proportionally.
A triangle varies from a square to a ziggurat sort of shape.  That's VERY cool, 
and apparently sounds great too. :-)
     
I have some practical questions:
     
So, how many comparators do you use?  Also, would you take positive CVs, 
and expect the wave to be centered about zero?  Actually, you probably have 
the "fixed" end of the ladder at -5v, and let the othe end vary from -5v to
+5v (or so).  At least for "useful" range.  So, a manual offset control hooked 
between +-5 volts, and an attenuated CV or two mixed into that should suffice?
     
Or am I missing something?
