The CP3A-O OSCILLATOR CONTROLLER provides dedicated control functions for oscillator modules within a Eurorack patch, letting you shape and manage pitch and modulation with more precision than patching directly. It’s designed to work alongside compatible oscillator modules as part of a larger vintage-style modular voice. The CP3A-O adds refined oscillator control to a modular rig, giving pitch and modulation the kind of precision that patching directly to an oscillator simply can’t match. Features: Authentic reproduction of the circuitry from the “Modular 55 and 35” Series Artist roster includes world’s most famous pop, rock and jazz musicians 4 switches allow you to send CV to 1 or more oscillators External input jack with dedicated attenuator control 3 switched and summed CV inputs for frequency control of VCO modules 3 parallel CV outputs can drive multiple 921A/B oscillator modules Eurorack specs: 8HP, 5mA +12V, 5mA -12V
