VCO Extra Companion

This VCO companion supplies several harmonics with different waveshape., You will find a square fifith you need to adjust the PW on the VCO to get it alone or mixed with the octave.

Trimmers adjust the sine and triangle offset.

My advice is to make the mixers with linear potentiometers to have a view of the harmonics 

This circuit has the same size as the VCO. I could provide double side pcb for 15€ in Europe. (Email)
