Behringer CP3A-O Oscillator Controller Module for Eurorack

The Behringer CP3A-O is an analog oscillator controller module designed for Eurorack modular synthesizer systems. Inspired by the circuitry of the classic Modular 55 and 35 systems, this module provides centralized control over oscillator pitch modulation and control voltage routing within modular synthesis environments.

The CP3A-O allows users to route control voltages to multiple voltage-controlled oscillators using four dedicated switches. These switches enable flexible routing of pitch control signals to one or more oscillators, making it easier to control multiple VCOs from a single control source or sequencer.

Three switched and summed CV inputs provide frequency control signals for connected oscillators, while an external input jack with its own attenuator allows additional modulation sources to be integrated into the signal path. The module also provides three parallel CV outputs capable of driving multiple oscillator modules such as the Behringer 921A and 921B.
