Brand: Dual
The Dual CS 601 is a high-end analog synthesizer that was released by the German company Dual in the late 1970s. It features two fully independent synthesizer sections, each with its own oscillator, filter, envelope, and LFO sections.This dual configuration allows for the creation of complex and rich sounds, with the ability to perform polyphonic or split-keyboard setups. The oscillator section offers a variety of waveforms, including sawtooth, square, and PWM (pulse width modulation) waves, as well as a white noise generator.The filter section is equipped with a resonant low-pass filter with cutoff frequency control, resonance control, and a self-oscillating mode. The envelopes have attack, decay, sustain, and release controls, while the LFO provides a low-frequency oscillation for modulation of various parameters.Other notable features of the CS 601 include a 32-note keybed, a unique modulation system that allows for the creation of complex matrix routings, and output sections for audio and control signals.Overall, the Dual CS 601 is a powerful and versatile synthesizer that remains highly sought-after by vintage synth enthusiasts and professional musicians due to its rich and complex sound capabilities.
