Unleash the power of innovation with the Sequential OB-6 Desktop 6-Voice Polyphonic Synthesizer. A masterful collaboration between synthesizer legends Dave Smith and Tom Oberheim, this compact module captures the essence of classic analog warmth while integrating modern enhancements. Its all-analog signal path is inspired by the revered SEM circuits, delivering lush, vibrant sounds that have defined generations.

With six discrete voices, each equipped with two voltage-controlled oscillators and a sub oscillator, the OB-6 offers a rich harmonic palette. The state-variable filter provides low-pass, high-pass, band-pass, and notch options for versatile sound shaping. Whether you're crafting fat bass lines or ethereal pads, this synth has the tonal depth to inspire.

The OB-6 stands out with its intuitive, knob-per-function interface, ensuring that every parameter is within reach for spontaneous creativity. Dive into the dual digital effects engines, offering reverb, delay, chorus, flanger, and faithful recreations of classic phase shifter and ring modulator effects, all while maintaining a pure analog path through true bypass.

For those seeking to expand their sonic possibilities, the OB-6 is equipped with Dave Smith's X-Mod feature, enabling dramatic modulations across multiple destinations. Meanwhile, the polyphonic step sequencer and arpeggiator provide endless rhythm and melodic possibilities, syncable to external MIDI for seamless integration into any setup.
