The Zero Point Oscillator is not your typical analog VCO or even your standard Thru-Zero FM VCO for that matter.

The core of the ZPO was developed through countless hours of experimentation involving Through-Zero modulation techniques. 

Through-Zero FM is a form of frequency modulation that produces much deeper and useful FM tones than a typical VCO can accomplish.

New techniques have been discovered that not only improve the performance of TZFM, but also grant additional benefits (explained in manual).
