Sequential Dave Smith OB6 Desktop Module 6-Voice Polyphonic Analog Synthesizer

The Sequential Dave Smith OB6 Desktop Module is a compact, six-voice polyphonic analogue synthesizer that delivers the classic Oberheim sound in a versatile desktop format. It contains the same audio circuitry as the keyboard version, making it ideal for integrating into an existing studio setup or modular system without requiring additional keyboard controllers. This module provides the full sonic character and tactile control of the original instrument in a space-saving design. The synthesizer features two discrete voltage-controlled oscillators per voice, plus a sub-oscillator, with continuously variable waveshapes including sawtooth, variable-width pulse, and triangle waves. Its sound is shaped by a classic, state-variable Oberheim-inspired filter offering low-pass, high-pass, band-pass, and notch modes, completing a fully analogue signal path. The front panel offers knob-per-function control with full-sized controls for immediate parameter adjustment, including a dedicated manual switch for live panel mode. A comprehensive dual effects section provides studio-quality reverbs, delays, chorus, and emulations of Tom Oberheim's original phase shifter and ring modulator, all operating at 24-bit/48kHz resolution with true analogue bypass. The OB6 Desktop Module is well-suited for musicians and producers seeking authentic vintage polyphonic synthesis in a modern, flexible package. It includes a polyphonic step sequencer with up to 64 steps, a multimode arpeggiator, and extensive modulation capabilities through its X-Mod system, which uses the filter envelope and oscillator 2 as modulation sources. With MIDI clock sync and a Poly Chain feature that allows pairing two units for twelve-voice polyphony, it integrates seamlessly into both studio and live performance environments. Its combination of immediate hands-on control, classic analogue warmth, and modern features makes it a compelling choice for sound design, composition, and performance.
