Behringer RS-9 Rhythm Sequencer
The Behringer RS-9 is a 52 HP Eurorack rhythm sequencer module that brings the powerful sequencing DNA of the RD-9 drum machine into a modular format. It features a 64-step sequencer across 10 independent tracks, perfect for triggering external drum modules, samplers, or any CV/gate gear. With dedicated trigger and accent outputs per track, plus advanced performance features like polymeter, probability, swing, ratchets, flam, step repeat, and note repeat, it excels at creating dynamic, human-feeling beats on the fly. Whether you're building classic analog drum patterns, experimental polyrhythms, or full songs with pattern chaining, the RS-9 offers deep sequencing power at a very accessible price point.

Key Features & Workflow
- 10 Independent Tracks — Each with its own trigger + accent output for dynamic control of external sound sources. Great for kick, snare, hats, toms, percussion, and even melodic triggers or basslines.
- Powerful 64-Step Sequencer — Flexible per-track step length (1–64), polymeter capabilities, and extensive memory (256 patterns / 16 songs) for full arrangements without a computer.
- Performance Tools — Swing for groove, probability for organic variation, ratchets and flam for added texture, step/note repeat, and real-time triggering. Random pattern generation helps spark ideas quickly.
- Modern Connectivity — MIDI/USB for DAW integration or external clocking, plus dedicated clock sync I/O and CV output for parameter automation or extra modulation.
- Modular Integration — Designed as a trigger brain for your rack. Patch the 10 triggers and accents to drum voices, envelopes, or anything that needs gates. Low power draw and solid mechanical feel make it case-friendly.
- Workflow — Classic step-button programming combined with real-time recording. Enter Pattern mode for beats, Song mode for chaining. Intuitive enough for quick jams but deep enough for serious composition.
- Best For — Live beat creation, hybrid setups (sequencing analog drums + modular), sketchbooking rhythms, and expanding smaller drum machines or samplers with more advanced sequencing.
The RS-9 shines as an affordable, dedicated rhythm sequencer that keeps the focus on hardware workflow and immediate creativity. It doesn't generate sounds internally — it's purely a control and trigger powerhouse meant to drive your existing gear.
