Divide the 128 CC values into 16 bins.  The first bin goes from 0-7,
second from 8-15, etc.  If you instead turn the amount down, you're
effectively multiplying the input CC by the percent.  Therefore, at
50%, 0-15->0, 16-31=8, ... 112-127=64.  I should have said 98% *amount*
instead of input.

38% is close, 6% to FINE pitch is miniscule, but important if you need
dead on tuning.  Most often it won't matter.

INPUT -------------->  100% -----> OUTPUT
       \---> LAG ---> -100% --/

The gain is just something to sum to.  It also has the nice effect of
amplifying the derivative signal so as to make it more noticeable. 
Quantize is simply the input.  It goes both to the output AND through
the LAG (inverted) to the OUTPUT (which is Gain4X in this case).

Use the same diagram as above.  INPUT would be pitch wheel.  OUTPUT
would still be Gain4X (cuz you need signal gain, the differentiator
output is not very hot).  Still use the Abs to make it always positive.
 Then route it to Chorus amount. (note that you have to have chorus set
to 1 in its page so as to enable it)

PtchWhl -> Gain4X +100%
PtchWhl -> Lag0In +100% 
Lag0    -> Gain4X -100%
Gain4X  -> Abs    +100%
Abs     -> Chorus +100%
