The Behringer System 55 921 Voltage Controlled Oscillator (VCO) is an analog module specifically designed for the Eurorack format. Inspired by the legendary VCOs of the 1970s, this module offers an authentic reproduction of the circuits from the Modular series. It is ideal for musicians and producers seeking the characteristic vintage sound found in many classic pop, rock, and jazz productions. The 921 VCO allows for a variety of sound generation through its six selectable waveforms, including sine, triangle, sawtooth, and square. With pulse width control and numerous CV and trig inputs, the module provides high flexibility and creative possibilities for sound design. The intuitive interface with eight knobs and switches allows real-time access to all important parameters, making it easy to integrate into existing setups.
