Dave Smith OB-6

The Dave Smith OB-6 is a modern, all-analog 6-voice polyphonic synthesizer. Paying tribute to the line of Tom Oberheim’s SEM 4-Voice & 8-Voice synthesizers, with several enhancements. Sporting true voltage-controlled oscillators, a classic Oberheim-inspired 2-pole, state-variable resonant filter, amplifiers, envelopes, and an LFO. While additional enhancements include a plethora of studio-quality effects, polyphonic step-sequencer, and arpeggiator. All of which can be synchronized internally or via the external MIDI clock.

Featuring four-octave, sem-weighted keys, the OB-6 offers velocity sensitivity and channel aftertouch. While the control panel offers knob-per-function control with no menu diving required. With 500 permanent factory programs and 500 user programs, the OB-6 is organized into 10 banks of 100 presets. Above all, the OB-6 offers an ideal combination of portability and power; perfect for the project studio or gigging musician.

Synth dreams are made of this

Furthermore, the Dave Smith OB-6 rocks 6 discrete analog voices along with 2 oscillators and a sub-oscillator per voice. While naturally, the OB-6 is equipped with Dave’s infamous X-mod (two sources, five destinations). On top of all that, you’ll find a 64-step polyphonic sequencer, two digital effects engines, and an advanced arpeggiator. With the knob-per-function an silky-smooth, semi-weighted keyboard to control all the firepower.

Heart of the beast: Oberheim’s classic SEM

While the original SEM (Synthesizer Expansion Module) formed the core of Tom’s renowned 4-Voice and 8-Voice synths of the 1970s. You’ll find the updated SEM is also the core of the OB-6 analog sound engine. Including two discrete voltage-controlled oscillators, and a sub-oscillator per voice; the OB-6 gives you the flexibility of waveshapes varying between sawtooth and variable-width pulse. While the OB-6’s oscillator 2 also sports a triangle wave. As well as the classic Oberheim-style state-variable, 2-pole resonant filter featuring lowpass, highpass, bandpass, and notch functionality. Completed by the OB-6’s voltage-controlled amplifiers.

X-Mod, Poly Step Sequencer, and Arpeggiator

Finally, the OB-6 is specced out with Dave Smith’s brilliant X-Mod. Making it easy to achieve killer sounds via modulation.The soureces being the filter envelope and oscillator 2. While the 5 destinations include oscillator 1, filter mode, and filter cut off. Then the polyphonic step sequencer lets you program polyphonic sequences complete with rests, all synced to the external midi clock.

Overall, the Dave Smith OB-6 is a fantastic analog keyboard synth. Paying tribute to the legendary Tom Oberheim SEM.
