Overview

Dave Smith OB-6 Desktop

The Dave Smith OB-6 desktop is a modern, all-analog 6-voice polyphonic synthesizer that pays tribute to Tom Oberheim’s SEM 4-voice and 8-voice synthesizers, but with several enhancements. The synth features true voltage-controlled oscillators, a classic Oberheim-inspired 2-pole, state-variable resonant filter, amplifiers, envelopes, and an LFO. Additional enhancements include studio-quality effects, a polyphonic step-sequencer, and an arpeggiator; all of which can be synchronized internally or via external MIDI clock.

The four-octave, semi-weighted keyboard offers velocity sensitivity and channel aftertouch, while the control panel offers knob-per-function control with no menu diving. There are 500 permanent factory programs and 500 user programs which are organized into 10 banks of 100 presets. The OB-6 offers an ideal combination of portability and power for the project studio or the gigging musician.

Two Legends. One Instrument

Both the OB-6 desktop module and OB-6 keyboard are 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.

Vintage SEM Tone

The Dave Smith OB-6 Desktop 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.

Dual Effects

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.

X-Mod and Poly Step Sequencing

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.

Easy to Program

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.

Easy to Play

This analog powerhouse is packed into a desktop module that’s small enough to fit in a backpack. It’s an ideal combination of portability and power for the project studio or the gigging musician.
