Wasn't there a module in the Electronotes PCC that was something like that?

It had an audio input, and audio output, a CV output, and a single toggle
switch.

When the switch was flipped one way, the audio input fed right to the audio
output, and the CV output was at 0V.  When the switch was the other way, the
CV output rose to 1V, and a divide-by-2 circuit was placed on the audio path.

It was intended to be patched into a VCO, with the square wave output tied
to the module input, and the CV to the VCO input.  Just flip the switch
until the oscillator is scaled.

Of course, calibrating the 1V output then becomes an issue...
