Great job! What does the skew function do to the square wave? Change the pulse width? I mean is it possible to achieve the classic PWM effect on this VCO?
By the way the octave shift knob sounds like not shifting 1 octave increments, I think needs a bit of retuning.
Skew does nothing on square wave, I think you can still obtain a decent pwm output putting the sine/triangle output into a comparator with variable reference level... again not a proper pwm output, but this vco is a bit funky anyway. And for the octave shift, yes, these are not exact increments,but while building it i was out of trimmers and used fixed partitors instead (silly idea I admit). Every time i shift octave i just retune manually the vco using the pitch slider.

I really like your panel designs! I also like how you've hardwired the functions rather than jacks for everything. Sounds great, too.
