Eurorack VCO Modules
Eurorack VCO modules are the life force of the modular synthesizer. VCO stands for voltage controlled oscillator and are designed to generate audio oscillations in specific frequency ranges.
Eurorack VCO modules are the life force of the modular synthesizer. VCO stands for voltage controlled oscillator and are designed to generate audio oscillations in specific frequency ranges.
Analog VCO’s are often relaxation oscillators which produce output signals including sine, saw, triangle and square waveforms. Eurorack VCOs provide the raw audio signal that passes through the modular synth rack.Showing 40 of 126 products
