VCNO is a noise oscillator, capable of producing full spectrum white noise. But that’s where its similarity to other noise generators stops. VCNO can be used like a VCO – you can modulate the pitch over CV and use its multiple outputs simultaneously, each with a distinct sonic character. Its method of generating noise is similar to that used in early computer sound chips, except it has been implemented here using discrete logic, without the use of software or microcontrollers.
