[sdiy] sineshaper and piece wise linear function update

[Jim Patchell]

    Not really cascaded, but connected in parrallel.  If you look at the circuit on M.C.'s
page, you will note that it shows dotted lines for expanding the breaks in both directions.  I
was already using a similar circuit for processing the control voltages for my vocal filter,
but, the breaks and gains were all fixed.  I was contemplating ways of making it adjustable
when Martin posted that schematic.  Like others, I was concerned about all the pots....but,
what the heck.  The number of breaks I picked was based more or less on how many pots I was
willing to put on an aluminum (american spelling) panel.

    I also saw the posibilities that a module like this implied.  It can be used to make a
crude limiter, control voltage processor, sin shaper, etc...

    I am going to try very hard to at least post the schematic this weekend.  The Great
American Train Show is in town, which is going to cause a bit of a distraction, but, I will try
to keep my priorties straight. ;^)
