About Behringer 921 VCO

Under the spotlight of modern music production, the 921 Legendary Analog Voltage Controlled Oscillator Module emerges as a sophisticated and innovative addition to the Eurorack landscape. Drawing inspiration from the iconic System 55, 35, and 15 synth modules of the early 70s, this module is a tribute to the discrete transistor designs that defined an era of sound. Its high-quality construction and advanced features make it a professional choice for artists and producers seeking that distinctive analog warmth and complexity in their compositions.

The 921 Legendary Analog VCO is a testament to the enduring legacy of modular synthesis, which revolutionized electronic music and continues to influence its evolution. With its six selectable waveforms-including sine, triangle, saw, inverted saw, square, and inverted square-this module offers unparalleled flexibility in shaping soundscapes. The Frequency and Range controls, along with the Scale and Coarse RNG switches, provide precise manipulation of the signal's tonality, allowing for nuanced adjustments that can breathe life into any track.

For those who crave depth and texture, the Rectangular Width knob invites you to delve into the realm of fat Pulse Width Modulation sounds. The module's extensive connectivity options, featuring three summed Frequency Control Inputs and multiple auxiliary and waveform outputs, facilitate the integration of modulation signals both into and out of the oscillator. This enables the creation of complex patches that can elevate your studio sessions or live performances to new heights.

Designed with the Eurorack enthusiast in mind, the 921 Legendary Analog VCO seamlessly integrates into any standard Eurorack case. The straightforward installation process involves connecting the power cables to the power supply and securing the module with the included screws, allowing for effortless incorporation alongside other synth modules.

Whether you are just beginning your modular synthesis journey or seeking to enhance your existing setup, the 921 Legendary Analog Voltage Controlled Oscillator Module stands as a high-quality, advanced tool in the arsenal of any musician dedicated to crafting extraordinary music. With its roots in the past and its technology at the forefront of today's electronic music scene, the 921 VCO by Behringer is an essential component for those who value the power of innovation and the allure of the legendary analog sound.
