Description
Behringer 921B Voltage Controlled Oscillator Eurorack Module
Behringer 921B Voltage Controlled Oscillator is an analog oscillator module designed for Eurorack modular synthesizer systems. It enables waveform generation for modular users, supporting audio tone creation and modulation workflows within patch-based environments. This makes it ideal for Eurorack setups where additional oscillator sources are required.
The module operates as a voltage controlled oscillator that can be driven by the 921A Oscillator Driver module or used independently as a free-running oscillator. It provides dedicated waveform outputs and synchronization capabilities for integration within modular signal chains.
Within a modular system, it can function as an audio oscillator for tone generation or as a low frequency oscillator for modulation. Its parallel link connections allow multiple oscillator modules to be connected and controlled together.
Key Features
- Analog VCO Module: Eurorack oscillator module designed for modular synthesizer systems
- Vintage Modular Circuitry: Reproduction of circuitry from classic Modular 55 and 35 systems
- Four Waveform Outputs: Dedicated sine, triangular, sawtooth, and rectangular outputs
- External Driver Compatibility: Can be controlled by the 921A Oscillator Driver module
- Free Running Operation: May also function independently as an oscillator or low frequency oscillator
- Oscillator Sync Input: Dedicated synchronization input with selectable strong or weak sync modes
- Parallel Link Connections: Frequency and width link jacks support connection to multiple oscillator modules
- Flexible Patch Routing: Frequency and width jacks can be used as external input and output connections
- Eurorack Compatibility: Designed for standard Eurorack systems with eight HP module width
