Dave Smith Instruments Announces OB-6 Desktop Analog Synth

Dave Smith Instruments has announced the OB-6 Desktop, a module version of their six-voice analog synthesizer. Like the keyboard version, it contains a sound engine based on Oberheim’s original SEM and features an all-analog signal path with discrete VCOs, VCAs, and filters. The one-knob-per-function front panel offers immediate access to almost all parameters.

Both the OB-6 desktop module and OB-6 keyboard are a collaboration between 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.

The OB-6 sound engine is inspired by Tom’s original SEM, the core of his 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 Kicker: “We’ve also added a poly chain feature so that any two OB-6s can be paired for 12-voice polyphony. That is a monstrously big sound,” boosts Dave Smith

Dave Smith Instruments’ OB-6 desktop module will be available sometime during the fall of 2016 for $2,299.
