Dive into the world of modular synthesis with the Behringer 921A Oscillator Driver Eurorack Synthesizer Module. This module is an authentic reproduction of the iconic 1970s Modular 55 and 35 series, providing you with the vintage tones cherished by legendary musicians. Whether you're replicating classic sounds or exploring new sonic landscapes, the 921A offers a robust foundation for your creative journey.

Designed for seamless integration, the 921A fits comfortably in a standard Eurorack case, allowing for a modular setup that's as unique as your musical vision. With the ability to control up to 12 Behringer 921B Oscillator modules simultaneously, this driver opens the door to creating complex and nuanced waveforms. The frequency control can be adjusted between semitones and octaves using the intuitive rocker switch, while the pulse width of the rectangular waveform is adjustable from a crisp 10% to a wide 90%, giving you complete control over your sound's harmonic content.

For those who love to experiment, the 921A doesn't stop at onboard controls. It features external modulation inputs, allowing you to patch in control voltages or other signals to modulate frequency and pulse width. This flexibility ensures that your sonic creations can grow in complexity and depth as you layer oscillator outputs, leading to truly unique auditory experiences.
