Behringer 921

Voltage Controlled Oscillator Eurorack Module

Create the synthesizer of your dreams with the Behringer 921 Voltage Controlled Oscillator, an authentic reproduction of the circuitry from the Moog Modular 55, 35, and 15 Series synthesizer, allowing you to build your very own unique synthesizer that can fit in a standard Eurorack case, for a very affordable price.

The 921 is a signal source featuring six waveforms, each with their own dedicated outputs. The VCO offers a broad frequency range and can be switched to an ultralow mode for LFO duties. The module includes a ribbon power cable and mounting screws.

Benefits

• Vintage-sounding 921 VCO module from the ’70s
• Authentic reproduction of the circuitry from the Modular 55, 35, and 15 Series
• Artist roster includes world’s most famous pop, rock and jazz musicians
• VCO features 6 selectable waveforms (sine, triangle, saw, inverted saw, square, and inverted square)
• Pulse-width control with 2 separate CV inputs for fat PWM sounds
• Switchable between sub audio (LFO) and audio rate (VCO) for extended flexibility
• VCO offers Frequency and Range controls plus 6 separate audio outputs, 5 CV inputs, and 2 trig inputs
• 8 controls and switches give you real-time access to all important parameters
• Eurorack specs: 14 HP, 50mA +12V, 50mA -12V

Controls

The 921 Voltage Controlled Oscillator module features six selectable waveforms (sine, triangle, saw, inverted saw, square, and inverted square). These can be adjusted via the Frequency and Range controls to change the tonality of your signal. Finer frequency control is provided via the Scale and Coarse RNG switches. Patch in some control voltages via the two CTRL IN jacks and adjust with the Rectangular Width knob to create some fat pulse-width-modulated sounds.

Inputs and Outputs

Multiple ins and outs are available on the 921 Voltage Controlled Oscillator. Three summed Frequency Control inputs, and auxiliary and waveform outputs can be used to introduce modulation signals into the 921 Voltage Controlled Oscillator and out to other modules, to create complex patches that are perfect for your next studio session or jam.
