 The Sync VCO is actually a pair of oscillators,​ a normal voltage controled oscillator and an other oscillator that syncronice the first one. It comes with a triangle and a square wave output.\\ The Sync VCO is actually a pair of oscillators,​ a normal voltage controled oscillator and an other oscillator that syncronice the first one.
