Description

Introducing the Dave Smith Instruments OB-6 Desktop Synthesizer, a powerful musical instrument that combines the influential talents of Dave Smith and Tom Oberheim. This desktop module has all the controls of the OB-6 keyboard, offering immediate ease of use and a layout that is both comfortable and intuitive. With its analog signal path and discrete VCOs and VCFs, the OB-6 delivers a massive, in-your-face sound that is authentically Oberheim.

This synthesizer is a dream-come-true for musicians, featuring the same sound engine that inspired Tom's original SEM, the core of his acclaimed 4-voice and 8-voice synthesizers. Two discrete voltage-controlled oscillators per voice with continuously variable waveshapes deliver a vintage SEM tone that is nothing short of amazing. The OB-6 also features a dual effects section that provides studio-quality reverbs, delays, chorus, flangers, along with faithful recreations of Tom's original phase shifter and ring modulator.

To further expand your tonal palette, the OB-6 includes an X-Mod and a polyphonic step sequencer that allows up to 64 steps and up to 6 notes per step. The synthesizer is easy to program with a knob-per-function front panel and includes 500 permanent factory programs and 500 rewritable user programs. Compact enough to fit in a backpack, this analog powerhouse is the perfect combination of portability and power.

Key Features:

  • Analog signal path with discrete VCOs and VCFs
  • Two discrete voltage-controlled oscillators per voice with continuously variable waveshapes

Critic Reviews

Dave Smith Instruments OB-6 review | MusicRadar

musicradar.com

The Dave Smith Instruments OB-6 Desktop Synthesizer is a triumph of vintage-modern fusion, offering the classic Oberheim sound with a modern twist, thanks to a 2-pole state-variable filter. The synth boasts excellent modulation capabilities and a sturdy build. While some may find the panel labeling less than ideal and the sequencer's transpose function cumbersome, these are minor setbacks in an otherwise stellar piece of equipment. Ideal for those seeking a textured, aggressive sound, the OB-6 stands out for its sonic character but may not be the chameleon-like instrument some users desire.

Sonic LAB: OB-6 Desktop Analog Poly Review

sonicstate.com

The OB-6 Desktop Synthesizer from Dave Smith Instruments delivers rich, analog tones with its classic Oberheim sound. Its standout features include a versatile SEM filter and effective modulation options, providing a lush palette of sounds. While the synth lacks some modern conveniences like multiple LFOs per voice and a split keyboard, its engaging sound and intuitive design more than compensate, appealing to both nostalgic and adventurous musicians. The price is steep, but the OB-6's blend of heritage and innovation makes it a worthwhile investment for serious synth enthusiasts.
