| - | The Sync VCO is actually a pair of oscillators, one normal voltage controled oscillator and an other not voltage controled 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.

| In changing the capacitores one can change the range for the oscillators. The value should be between 10 and 50nF.\\ | In changing the capacitores one can change the range for the oscillators. The value should be between 10 and 50nF.\\ | ||
