   This relates to a current AH thread on Serge CV inputs. Going through
   their catalog it seems that there's a lot of modules that have CV's
   with CV amount knobs that have + and - amount (depth). When the knob
   is centered, the CV has no effect, when it's all the way to the right
   it has max "+" effect, all the way to the left, it has a max inverted
   effect.

   It seems like there must be a simple way to do this - but I'm not
   savvy enough to figure it out off the top of my head. 

   How about this:

Way too complicated.  Try this:

            +---vvvv---+  
            |  | \      |
            |  |  \     |
   +--vvvv--+--|-  \    |
---+           |    >---+----
   +--+    +---|+  / 
      |    |   |  /
      <    |   | /
      <<---+
      <
      |
     gnd

R's are equal and some reasonable value like 50k.  The pot can be any
reasonable value, like 100k, linear taper.
