Sequential OB-6 Desktop Module

The Sequential OB-6 Desktop Module delivers the legendary Oberheim® analog sound in a compact, portable desktop format. Developed through the iconic collaboration between Dave Smith and Tom Oberheim, the OB-6 combines the unmistakable warmth and character of the classic Oberheim SEM synthesizers with modern performance features, making it an exceptional choice for professional musicians, producers, and sound designers. Despite its compact size, the desktop module features the same analog sound engine and intuitive knob-per-function interface as the OB-6 keyboard version, ensuring immediate hands-on control without menu diving.

Featuring 6-voice polyphony, two discrete voltage-controlled oscillators (VCOs) plus a sub-oscillator per voice, a classic SEM-inspired 2-pole state-variable filter, stereo analog distortion, and dual studio-quality digital effects, the OB-6 Desktop delivers everything from lush vintage pads and expressive brass sounds to powerful basses and cutting-edge leads. Additional features such as a 64-step polyphonic sequencer, arpeggiator, X-Mod, and Poly Chain support for expanding to 12 voices make it equally suited for studio production and live performance.
