dVco
dVco stands for digital voltage-controlled oscillator, a type of oscillator used in electronic music synthesis and related fields. A dVco generates an audio-rate waveform digitally and uses a control voltage input to set its pitch, typically following a 1V per octave convention in modular systems. Unlike many analog VCOs, the core waveform for a dVco is produced by a digital core and converted to an analogue signal by a DAC and output stage.
Common digital cores include direct digital synthesis (DDS) with a phase accumulator, or wavetable and algorithmic
Advantages of dVcos include improved frequency stability and tracking across temperature, high precision, and broad timbral
In practice, dVcos are widely used in modular synthesizers, digital keyboards, and audio workstations where stable
