I have a scheme to control them via MIDI for a paraphonic sort of deal, but I'm looking at options to be able to close the switches via a pitch CV so the module is more flexible.

Are you still working on the top octave string synthesizer? I thought that's why you needed a switch for every key, so that potentially every oscillator could be mixed in. If that's what you're building, then using a single CV to control the switches would be incredibly limiting, because then the setup would be mono.

Maybe the shorter question would be, what kind of a module are you trying to build, exactly? There are always many ways to solve the same problem, and, of course, even more ways to solve several different problems.
