The OB-6 represents the culmination of a once-in-a-lifetime collaboration between synth design pioneers Dave Smith and Tom Oberheim. This 6-voice polyphonic powerhouse harnesses the best of vintage and modern analog synthesis into one formidable instrument. Whether exploring vast pads, growling basses or searing leads, the OB-6 delivers the soul-stirring sound that only true voltage-controlled oscillators can produce.

Pure, Vintage-Inspired Analog Tone

At the heart of the OB-6 beats an all-analog signal path directly descended from Tom Oberheim's legendary SEM design. Each of its six discrete voices contains two oscillators plus a sub-oscillator per voice, capable of generating classic waveshapes like triangle, sawtooth and variable-width pulses with continuously variable shapes. The state-variable filter provides precise tone-sculpting, while the voltage-controlled amplifiers shape harmonically rich envelopes. You'll experience the same powerful, in-your-face character that made Oberheim's vintage polysynths so iconic.

Responsive and Expressive Polyphonic Performance

Bolstered by the latest OS updates from Sequential, the OB-6 offers groundbreaking expressive capabilities through MPE (MIDI Polyphonic Expression) support. This technology allows the OB-6 to interface with multidimensional controllers like the Expressive E Osmose and Korg Keystage Controller for nuanced per-note articulation. The synth's semi-weighted keyboard with velocity and channel aftertouch further enhances the responsive, dynamic feel.

Iconic Effects and Sequencing Power

The OB-6 delivers the complete vintage Oberheim experience with faithful recreations of Tom's legendary effects. The phase shifter and ring modulator provide otherworldly timbres, while the 64-step polyphonic step sequencer allows you to effortlessly create intricate melodic lines and rhythmic patterns. Modulation sources like the LFO and envelopes can be freely assigned via the X-Mod matrix, enabling complex and evolving sounds. The full-featured arpeggiator inspires new melodic ideas at the touch of a button.

Solid Hardware and Included Essentials

The OB-6 comes bundled with a sustain pedal for enhanced playability, an adjustable X-style bench for optimal positioning and a heavy-duty keyboard stand capable of supporting up to 132 lb. This bundle provides everything you need to integrate the OB-6 seamlessly into your creative rig.
