Hi M.
Another idea, which is rather 'thinking out loud', so perhaps a little tricky in practice (and assumes CV to be inverted is always positive!): if you have an A-132 and a source of negative CV (perhaps an A-174 joystick: max neg X or Y is about -4.5V from memory), you could patch this negative voltage to 'sig in' on 132, and the CV to be inverted into 'CV1': 'sig out' is now a scaled, inverted version of CV1. This may require a lot of 'tweaking' of either (or both) the neg CV source and gain of CV to be inverted to get the scaling right! (If you don't have a 174, you could get approx -5V by inverting the max output from a 129/3 or a 176, and having used half a 175 to do this, you'd need to use *both* halves of the 132 to recover the other inverted signal...!!! )
