I finally posted my Subharmonicon emulator version 5 that relies on docB Formula One to compute sub oscillator V/Oct CV based on incoming primary VCO/Oct CV and sub harmonic divisor settings.
Formula One was a joy to use, and having multiple polyphonic inputs and outputs really expanded what I could do with it. It enabled me to easily add the new detuned unison feature, as well as output the computed harmonic divisor for dynamic display. I could not do that with a single instance of the Frank Buss Formula.
