The OB-6 is a once-in-a-lifetime collaboration between the two most influential designers in poly synth history, Dave Smith and Tom Oberheim. The OB-6 takes the classic bold Tom Oberheim sound — with its true voltage-controlled oscillators, 2-pole filter, and amplifiers — and adds modern enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. No other modern analog poly synth can boast such a pedigree or such a massive, in-your-face sonic signature.
The OB-6 sound engine is inspired by Tom’s original SEM, the core of his acclaimed 4-voice and 8- voice synthesizers. It features two discrete voltage-controlled oscillators (plus sub-oscillator) per voice with continuously variable waveshapes (sawtooth and variable-width pulse, plus a triangle wave on oscillator 2). The classic Oberheim-inspired 2-pole, state-variable, resonant filter provides low-pass, high-pass, band-pass, and notch functionality. Voltage-controlled amplifiers complete the all-analog signal path.
The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus, flangers, and faithful recreations of Tom’s original phase shifter and ring modulator. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analog signal path.
Also present is X-Mod, which expands the tonal palette and makes it easy to create dramatic and unconventional sounds. Modulation sources are filter envelope and oscillator 2, both with bi-polar control. Destinations include oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, and filter mode. The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create sequences polyphonically, with rests, and sync to an external MIDI clock. The full-featured arpeggiator can be synced to external MIDI clock as well. Unison mode features configurable voice count (1-6 voices), chord memory, and key modes.
The knob-per-function front panel puts virtually all OB-6 functions at your fingertips. Included are 500 permanent factory programs and 500 rewritable user programs. Turning on the Manual button enables live panel mode, in which the sound of the OB-6 switches to its current front panel settings. In this state, what you see is what you hear.
This analog powerhouse is packed into a four-octave, semi-weighted keyboard with velocity and channel aftertouch, making it perfect for stage or studio.
Sequential is helmed by legendary instrument designer and Grammy-winner Dave Smith, the original founder of Sequential Circuits in the mid-70s. Dave designed the Prophet-5, the world’s first fully-programmable polyphonic synth—and the first musical instrument with an embedded microprocessor.
Dave is generally known as the driving force behind the generation of the MIDI specification in 1981. It was Dave, in fact, who coined the acronym. In 1987 he was named a Fellow of the Audio Engineering Society (AES) for his continuing work in the area of music synthesis. After Sequential, Dave was President of DSD, Inc, an R&D division of Yamaha, where he worked on physical modeling synthesis and software synthesizer concepts. He then started the Korg R&D group in California, producing the Wavestation products and other technology.
He took over as President at Seer Systems and developed the first soft synth for Intel in 1994, followed by the first fully professional soft synth, Reality, released in 1997.
Realizing the limitations of software, Dave returned to hardware and started Dave Smith Instruments, which released the Evolver hybrid analog/digital synthesizer in 2002. Since then the Sequential product lineup has grown to include the Prophet X, Prophet Rev2, Prophet-6, OB-6, Pro 2, and Prophet 12 synthesizers, as well as the Tempest drum machine, co-designed with friend and fellow electronic instrument designer Roger Linn.
