Frequency in Hz to 1/v Octave

Derk Mauer's icon

Is there a method of converting frequency values in Hz to 1v/Octave ?

I would love to send frequency values from my patch out through my Expert Sleepers ES-8. It works fine with equal temperament, but since I'd like to use microtonal scales, I'm wondering how best to do this.

you simply scale note range to voltage.

it only depends if your voltage is

-5 ~ 5 , or 0 ~ 5 , 0 ~ 10 etc volt based and what you set as reference

frequency or note for v = 0.

for example for cv range -5 ~ 5 / v 0 = C4 (midi note 60) (261.625565 Hz)

zmap 0 120 -5 5

you send either frequencies to ftom 0. or notes as float

like 60.21
