Hi. I'm building a clone of the buchla 281 function generator which is
basically a set of voltage controlled attack-release generators where
each pair has an extra OR output. I have chosen to replace this OR
output with a CGS Analog Logic Board so I can also have the AND
function and external inputs.
Please see my panel layout here:

See the little knob in the middle? That and the 8 jacks below it
comprise the analog logic section of the module. The pot is a dual
gang and controls how much of envelope generator B goes into input 1
of the AND and how much of EG B goes into input 1 of the OR. Now my
question is: When this pot is turned all the way off, will the fact
that the inputs are then connected to ground interfere with the
pulldown resistors that turn off unused inputs to the logic module? Or
is it just the same as no input?
