Polyphonic Analogue Synthesiser Sequential OB-6 6-voice, 2-oscillator

Sequential OB-6 is a polyphonic analogue synthesiser with six-voice polyphony and a two-oscillator architecture. It reproduces a classic analogue signal path with discrete circuitry and provides resonant multimode filters, flexible envelope generators, LFOs and extensive modulation routing. The instrument is designed for studio production and live performance, capable of producing rich pads, cutting leads, punchy basses and evolving textures across a wide tonal range.

Advantages

The OB-6 combines the warmth and character of an analogue voice architecture with modern modulation options and intuitive hands-on controls. Its six independent voices and two oscillators per voice deliver dense ensemble sounds and complex detuning possibilities while resonant multimode filters shape timbre precisely. Built-in modulation routing and multiple LFOs allow detailed sound design without relying solely on menu navigation, and front-panel accessibility supports quick patch creation and live tweaking.

Suitable for

• Studio synthesis and sound design for electronic, ambient and cinematic music
• Live keyboard rigs and tactile performance setups
• Creating pads, leads, basslines and evolving textures
• Hybrid setups where analogue character is recorded or processed through modern DAWs

Key specifications

• Voice architecture: 6-voice polyphony
• Oscillators: 2 analogue oscillators per voice with detune and waveform options
• Filters: resonant multimode filtering with selectable response types
• Modulation: multiple LFOs and flexible routing for pitch, filter and amplitude modulation
• Envelopes: dedicated envelope generators for amplitude and filter control
• Controls: comprehensive front-panel knobs and switches for real-time sound shaping
• I/O: standard audio outputs and modern control connectivity suitable for studio and stage

How to use

Start by selecting or initializing a patch, then shape the primary timbre using the two oscillators: choose waveforms, adjust tuning and set detune to achieve thicker sounds. Route the signal through the multimode filter and set cutoff and resonance to define the character. Use the envelope generators to control the filter and amplifier contours, and apply LFOs to add movement to pitch, filter or amplitude. Save user patches after tweaking for recall during studio sessions or performances. When integrating with a DAW, use the audio outputs and available control connections to record and automate parameters.

Usage recommendations

For best results in both studio and live settings, use balanced outputs and quality cables to preserve analogue signal integrity. Employ modest amounts of external processing—EQ, compression and tasteful reverb or delay—to enhance the OB-6's natural warmth without masking its analogue character. Regularly save patches and document settings when preparing a live set to ensure consistent recall.
