Another aproach that's sometimes used is to include a control voltage mixer stage that allows one to pan between inverted and non-inverted control voltages, with the centre position resulting in a cancellation (i.e., no CV out). The EH-Y-Triggered Filter uses this approach. I've seen schematics of theYTF posted, but the schematic was not condusive to reverse engineering. I have a schematic for such a CV "pan" circuit in a back issue of Electronics Today. I'll see if I can scan it when I get back from holidays.
Incidentally, this approach allows the CV pan/balance control to double as an "intensity" control. Now that I think of it, parallels to the Big Muff Pi tone control are appropos:the amount of each type of output depends on how far clockwise or counter-clockwise the control is turned.
