Precision Processing Toolbox

XY (polarizer channel)
The top section is a voltage-controlled “polarizer” or more accurately, a four quadrant multiplier.. It multiplies two signals, “X” and “Y” . The X(Y) output is the product of these two sources. Unpatched, the Y input is normalized to an offset voltage, and thus will act as a standard processing channel when unpatched, giving X1 when fully CW and X-1 fully CCW. Patching a source into the Y INPUT defeats this normalization, and the “Y AMT” knob will now scale (multiply) the source patched into Y, giving Y1 when fully CW and Y-1 fully CCW. This is useful in that it allows the top section to be easily patched as a standard VCA with a positive going CV.

A->B (crossfader channel)
The middle section is a linear crossfader. The knob and A->B CV input sum, and select A to B and anywhere in between.
The ‘REF’ toggle, when engaged, routes a selectable offset to input A’s normalization- This allows you to use the crossfade channel as a voltage "mirror" , for instance..

Z (attenuverter/ offsetter channel)
The bottom section is simply another processing channel with an offset normalled to it’s input, acting as a manual offset control when unpatched. Patching into Z defeats this normalization, and Z AMT knob will now multiply the Z input, giving Z1 when fully CW and Z-1 when fully CCW. An LED indicates output amplitude and polarity.

There are two SUM outputs, “∑” and the complementary “-∑” . The SUMs are a summation of the three processing sections. Patching any of the three sections’ outputs independently removes them from the SUM outputs. This scheme allows for flexibility using the channels independently, for example, using Z as an offset voltage someplace in a patch- as well as prevents loopback issues when patching Cluster back into it's self- if, say, for instance you wanted to use XY as a ring-mod and send it to one of the crossfade inputs to have a VCA'd ring-mod, or vice-versa, you won't be adding XY to the SUM twice.
