SDS-3 Drum Synth: The Behringer Analog Revival of a Simmons Classic
Behringer’s at it again — this time resurrecting one of the most distinctive drum synths of the 1970s: the Simmons SDS-3. Modestly priced, the new SDS-3 channels that unmistakable analog punch and laser-zap tone that defined early electronic percussion, from disco toms to experimental electronic thuds. It’s not a groovebox or a drum machine, but a true analog sound generator that rewards tweaking, patching, and exploration. For anyone chasing the tactile feel of hardware drums, the SDS-3 looks like a surprisingly faithful revival — a Eurorack-sized unit with four channels of pure analog circuitry, a diode-ladder filter, and modern comforts like MIDI, USB, and trigger inputs. It’s another reminder that Behringer’s mission to clone history isn’t slowing down — and this time, it’s hitting a nostalgic sweet spot for producers who want something dirtier and more hands-on than samples.

A Classic Reborn
The original Simmons SDS-3, released in the early ’70s, was a strange and wonderful machine — a fully analog percussion synthesizer that predated the iconic hexagonal pad kits of the ’80s. Designed by Dave Simmons, it used oscillators, filters, and noise generators to sculpt drum tones that sounded more alien than acoustic. Those signature “pew pew” sounds became a calling card for early electronic acts and shaped the DNA of later Simmons units like the SDS-V.
Fast forward fifty years, and Behringer’s approach is clear: rebuild the past for modern workflows and prices. Their take on the SDS-3 fits that mold perfectly — Eurorack-ready, affordable, and dripping with character. Unlike most drum machines that prioritize sequencing and preset recall, this one invites players to perform sound design in real time. It’s as much a tribute as it is a playground for the new wave of analog percussion enthusiasts.
Features
At its core, the Behringer SDS-3 delivers five analog channels — four independent drum voices plus a dedicated effects channel — each with its own set of classic parameters. You get pitch, bend, decay, filter resonance, and noise level controls, giving you the flexibility to create everything from tight, snappy hits to deep, resonant booms. It’s modeled directly on the original Simmons circuitry, complete with a self-oscillating diode-ladder filter that adds that unmistakable vintage grit.
Connectivity-wise, Behringer modernized the design just enough to make it play nicely with today’s setups. The SDS-3 is Eurorack-friendly (70HP), can be triggered via MIDI or analog inputs, and includes USB-B for simple DAW integration. Each channel has its own output, and there’s a mix out for quick routing to an interface or live rig. The build looks solid for its price point, and the layout’s refreshingly simple — no screens, no menus, just knobs and immediate feedback. With its modest price tag, it’s aimed squarely at producers who want hands-on analog drum synthesis without breaking the bank.
Sound & Use Cases
The SDS-3 leans fully into analog texture — those recognizable pew and thwack tones that made early Simmons gear both futuristic and primal. It can handle the essentials, from punchy electro kicks and boomy toms to sharp snares and metallic zaps, but it also thrives when pushed into weird territory. Crank the filter resonance, dial in long decays, or modulate the noise and you’ll stumble into percussive drones, laser bursts, and warped sci-fi accents that sound like they were sampled from vintage Kraftwerk or early industrial records.
In a studio setup, it’s ideal for layering over drum machines or sampling into an MPC or DAW for analog grit. Live performers and modular artists will appreciate the hands-on immediacy — every knob tweak translates instantly into sound. It’s not built to replace a full drum machine; there’s no sequencer, memory, or effects processing here. Instead, it’s a creative tool for shaping raw analog percussion and responding in real time. If you’re someone who likes your drums alive and unpredictable, the SDS-3’s simplicity becomes a strength.
Modern vs Vintage
Behringer’s SDS-3 doesn’t just recreate the 1970s circuitry — it adapts it for modern workflows without losing its analog soul. The original Simmons unit was large, temperamental, and limited to CV triggers from external pads. Here, Behringer scales it down to a compact Eurorack format, adds MIDI and USB connectivity, and tightens up the tuning and noise performance for consistency. The result is a synth that behaves reliably in a 2025 studio while still retaining the chaotic warmth and punch that made the vintage gear so addictive.
That said, the redesign does shift the experience slightly. You don’t get the iconic Simmons hex pads, and the panel layout favors efficiency over nostalgia. Purists might miss the quirks of the original hardware, but for most modern producers, the trade-off is worth it — this version actually fits on your desk, syncs with your DAW, and can slot right into a modular rack. It’s a genuine analog reissue with modern usability, not just a retro novelty.
Pros & Cons
Pros
Authentic analog Simmons-style sound with rich filter character
Modest price makes it one of the cheapest true drum synths on the market
Eurorack compatibility (70HP) and modern connectivity via MIDI and USB
Hands-on, knob-per-function layout encourages real-time performance
Great for techno, industrial, and experimental percussion sound design
Cons
No sequencer, memory, or patch recall — everything is manual
Four drum voices only, may feel limited for complex rhythms
Build quality and power supply remain unconfirmed until release
Not suited for producers who want instant “drum machine” workflow or presets
Verdict
The Behringer SDS-3 is a surprisingly inspired throwback — not just another clone, but a reminder of how fun and raw analog percussion can be. It nails the essence of the original Simmons design: quick to tweak, endlessly expressive, and unapologetically weird. The lack of sequencing or memory might seem limiting at first, but that’s exactly what makes it so engaging. You’re encouraged to play the knobs, not rely on presets, and that interaction gives every hit a slightly human, unpredictable energy.
It’s a perfect fit for modular users, hardware-focused producers, and live performers who want an affordable analog percussion voice that can sound futuristic or completely unhinged. On the other hand, those who prefer instant recall, tight DAW integration, or sample-heavy workflows might find it too stripped back. At this price, though, it’s hard to ignore — the SDS-3 offers a rare chance to own a genuine piece of analog drum history reimagined for today’s setups.
