condition: excellent
make / manufacturer: Dave Smith
model name / number: OB6
I'm the original owner of this in excellent condition OB6. Comes with manual, original box, power supply and keyboard cover from Digital Deck Covers. Priced competitively. This is an amazing sounding keyboard in excellent condition.

The Sequential OB-6 rocks six discrete analog voices with two oscillators and a sub oscillator per voice. Naturally, OB-6 is equipped with Dave's infamous X-mod (two sources, five destinations). On top of all that, there's a 64-step polyphonic step sequencer, two digital effects engines (with studio-grade reverbs, delays, chorus, flangers, and accurate re-creations of Mr. Oberheim's renowned ring mod and phase shifter), and an advanced arpeggiator. To control all this firepower, you have a knob-per-function top panel and a silky-smooth, semi-weighted, velocity- and aftertouch-enabled keyboard. From funk-laden basses and snarling, in-your-face leads to gloriously celestial pads, the OB-6 will make your synth dreams come true.

Heart of the beast: Oberheim's classic SEM
Oberheim's original SEM (Synthesizer Expansion Module) formed the core of Tom's renowned 4-Voice and 8-Voice synths of the 1970s. The SEM, in updated form, is also the core of the OB-6 analog sound engine. With two discrete voltage-controlled oscillators and a sub oscillator per voice, the OB-6 gives you the flexibility of waveshapes that are continuously variable between sawtooth and variable-width pulse. Oscillator 2 also sports a triangle wave. The classic Oberheim-style state-variable, 2-pole resonant filter features lowpass, highpass, bandpass, and notch functionality. The all-analog signal path is completed by the OB-6's voltage-controlled amplifiers.

X-Mod, Poly Step Sequencer, and Arpeggiator
The OB-6 is spec'd out with Dave Smith's brilliant X-Mod, which makes it easy to achieve killer sounds via modulation. The filter envelope and oscillator 2 are the sources, and they both give you bi-polar control. The five destinations are oscillator 1 frequency, oscillator 1 waveshape, oscillator 1 pulse-width, filter mode, and filter cutoff. The polyphonic step sequencer lets you program polyphonic sequences (up to 64 steps, up to six notes per step), complete with rests, and sync them to external MIDI clock. The full-function arpeggiator can also be synced to external MIDI clock. You can configure the OB-6's Unison Mode voice count for up to six voices; it also features a chord memory and key modes.
