You wouldn’t need such extreme precision if you had feedback from the final pitch output to the quantizer that is generating this CV. You’d hen have an “autotune” system that was capable of microtonal playing, and all it would need would be an accurate way to measure the incoming pitch, and a load of big look-up tables of all the scales it could play.
But again…at this point it’s just screaming DIGITAL!
