Suitable for studio production and live performance, it covers pads, leads, basses and evolving textures.

## Long description

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.
