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 as will be explained. The ZPO\'s modulation section is a hybrid involving both TZFM (frequency modulation) and TZAM (amplitude modulation). Coupling these two techniques substantially expands the performance and tonal shaping possibilities, beyond traditional TZFM. The results are more stable and balanced across the modulation bandwidth and both TZFM and TZAM can function together or independently, and anywhere in between.
