That is a longish technical discussion.

Zero is an important number in math because zero times 
anything is zero, so you can use it to shut modulation sources 
"off".

There are two types of inputs traditionally used. One is a 
uni-polar that goes from zero to a positive value. This makes it 
easy to find the zero point and shut modulation completely off, 
without unplugging a patch cord. In my experience, this is more 
useful for live performance. In live performance with a modular, 
you usually have multiple patches set up before hand, and turn 
them on and off with the knobs.

The other is a bi-polar input that has positive and negative on 
one knob. The bi-polar design makes it harder to find the zero 
point. The null point usualy does not shut completely off, and you 
need to unplug the patch cord for best isolation. I feel this is less 
handy for live performance.

The Wiard provides negative going outputs rather than negative 
going inputs. The Envelator and Mixolator both have negative 
going outputs.

The Blacet Mixer/processor has bi-polar inputs, but they are an 
improved design, with center detent pots, and a null trimpot. 
They fix the problems with traditional bipolar input designs and I 
highly recommend the module.
