    1. This circuit is not designed to be CV controlable. But there are some ways you could try. Inserting a voltage at U1 pin 2 (through a 100k resistor for example) might modify the frequency and the ratio (Pulse instead of square wave). Higher voltage, lower freq. But you need to test it as I only simulated it.
      An other option would be to replace or add in parallel to the frequency potentiometer a digital potentiometer, or an OTA in variable resistance configuration.
      Basically, this looks more complicated than using a simple saw core VCO, in my opinion.
