How to use
Connect the Sequential OB-6 SEQ to monitors or an audio interface via its audio outputs and attach a MIDI controller or USB cable for external sequencing. Use the front-panel controls to select or edit patches, adjust oscillator tuning and shape the filter and envelope settings. Combine modulation sources to create evolving textures; save your settings where available and recall them through MIDI program change or the internal patch storage. When integrating with a DAW, set the OB-6 SEQ as an external instrument to record its audio output while synchronizing tempo via MIDI clock.
Usage recommendations
For balanced sound and minimal noise, use quality shielded cables and set gain stages in your audio interface to avoid clipping. When performing, map frequently used parameters to your MIDI controller or footswitch for hands-free adjustments. In the studio, experiment with layering the OB-6 SEQ’s analog-rich tones with digital textures to exploit the hybrid architecture.
