The following Sapphire modules allow you to toggle the polarity of the voltage on the X, Y, and/or Z output ports:
All of these modules have XYZP output ports, where the XYZ ports are monophonic and the P port has 3 channels.
In each case, the X, Y, and Z output ports of these modules allow right-clicking to toggle an option labeled "Flip voltage polarity".
When you right-click on any X, Y, Z output port and enable voltage flipping, the voltage coming out of that port will be inverted. For example, if X was sending +5.3V, it would now immediately become -5.3V.
Toggled voltage values are reflected in the polyphonic output port P. In the example above, if P = [+5.3, -1.7, +0.2], after toggling the X polarity, P would be [-5.3, -1.7, +0.2].
Toggled voltage values are also reflected in the vector that these modules send to any Tricorder-like module immediately to their right.
The purpose of voltage flipping is to allow the patch designer to select from
