The Sequential OB-6 49-Key 6-Voice Polyphonic Synthesizer is a masterpiece born from the minds of synthesizer legends Dave Smith and Tom Oberheim. This analog powerhouse merges vintage charm with modern enhancements, offering musicians an expansive playground for sound creation. Inspired by the classic SEM circuits, the OB-6 houses six discrete analog voices, each supported by two voltage-controlled oscillators plus a sub oscillator, delivering a rich tapestry of sound possibilities.

At its core, the OB-6 features a state-variable filter reminiscent of Oberheim's iconic designs, providing low-pass, high-pass, band-pass, and notch filter options. Its robust digital effects engine includes studio-quality reverbs, delay, chorus, and recreations of Oberheim's legendary phase shifter and ring modulator. The X-mod section opens up further sound sculpting opportunities, making it simple to achieve unique and dramatic tones.

For composers and live performers, the OB-6 does not disappoint. The 64-step polyphonic step sequencer and versatile arpeggiator, both syncable to external MIDI, allow for intricate pattern creation and real-time performance enhancements. The user-friendly interface, with its knob-per-function layout, ensures that creativity flows uninterrupted by menu-diving. Whether in the studio or on stage, the OB-6's 49-note semi-weighted keyboard with velocity and aftertouch makes it a joy to play, providing expressive control over your musical creations.
