921 Voltage Controlled Oscillator

Behringer 921

An essential part of a modular synthesizer setup, the Behringer 921 captures the classic modular VCO in all its glory. Set the overall frequency using the range switch and frequency detune, with +/-12 semitones or +/-6 octaves. Switch the audio VCO into sub-audio territory using the corresponding switch. Control the pulse width with two separate CV signals for huge PWM sounds.

Four preset waveform outputs are arranged on the bottom and feature sine, triangle, sawtooth, and pulse waveforms. An additional auxiliary waveform features six different waveforms and integrated level control with positive and negative outputs. Reset the phase of the oscillator with the clamping input, otherwise known as hard sync, available on both S-trig (gate) and the dedicated V-trig signals found on Behringer System 55 modules. Get a vintage-style oscillator in your Eurorack case with this oscillator from Behringer.
