introduction

im new to this forum

is it possible to exchange one Tune Poti with a octave switch ( e.g octave switch from elby design ) just a rotary with generates 0 - 8 V in 1V steps
Is the Tune Poti just a poti with is connected to 0 and 10 V and generates the input voltages for the freq... if that is so i can do a octave switch instead
or is it possible to add another flying resistor to the sum input of freq cv control to get another control input

normaly i can find out such stuff by myself but i did not own the pcb yet and i need to think about this during panel layout design ( i build panels by my own in 3he ) because for the octa switch i need some extra space
