Behringer RD-9 Review UK 2026

Key specifications

What the RD-9 actually is

The RD-9 is Behringer's recreation of the Roland TR-909, the drum machine behind a large share of house and techno since the late 1980s. It came out in 2021 and follows the original's split design. The bass drum, snare, three toms, rim shot and clap are analogue circuits. The closed hat, open hat, crash and ride are samples, which is also how Roland built the 909.

That split matters when you listen. The analogue voices respond to the tune, decay and attack controls the way a 909 does, and they can be pushed into the long, booming kicks and snappy snares the genre runs on. The cymbals and hats behave like samples: you get level, tune and decay, but not the same degree of reshaping.

Sound shaping, voice by voice

Control is generous on the voices that matter most and minimal on the rest.

• Bass drum: tune, level, attack, decay, pitch and pitch depth. This is the voice most people buy a 909 for, and it gets six controls.
• Snare: tune, level, tone and snappy.
• Toms: level, tuning and decay for each.
• Rim shot and clap: level only.
• Hats: tune and level, with separate decay for closed and open.
• Crash and ride: level and tune.

On top of the voices sit two additions the 909 never had. The Wave Designer adds or cuts attack (plus or minus 15 dB) and sustain (plus or minus 24 dB), with a per-voice send, so you can sharpen a kick's click or shorten a clap's tail without reaching for a plug-in. The filter is a 12 dB state-variable design that switches between low-pass and high-pass, with resonance and a cutoff range of 10 Hz to 15 kHz. You can record filter sweeps into a pattern, which is the easiest way to get a build-up out of the box on its own.

Sequencer: where it beats the original

The RD-9's sequencer is the strongest argument for it over a used TR-909. Patterns run up to 64 steps, set in blocks of 16, and you can store 16 songs of 16 patterns each, 256 patterns in all.

The extras are what keep patterns moving:

• Swing and flam from the data encoder.
• Step probability, so a hat or ghost snare plays only some of the time.
• Loop Overlay, which gives each track its own length. A 12-step hat line against a 16-step kick drifts in and out of phase without you programming every bar.
• Step repeat and note repeat at 1/2, 1/4 and 1/8, which suits rolls and live fills.
• Autofill, mute and solo, and a Pattern Launch mode for live sets.

If you want the original experience, Authentic mode turns off the Wave Designer, filter, repeats and probability. That is a sensible touch: you can learn the classic workflow first and add the modern tools later.

Connections and setup

This is a studio-friendly machine. There is a balanced mono main out, a headphone socket and a return input. The real asset is the ten individual voice outputs, which let you send the kick, snare and claps to separate channels for their own EQ and compression. That is how 909 parts are usually mixed on records.

For sync there is MIDI In, Out and Thru on 5-pin DIN, class-compliant USB MIDI (no audio over USB, so you still need an audio interface to record it), 3.5 mm clock in and out, and three trigger outputs at +5 V for modular systems or older analogue gear. The sync source can be internal, MIDI, USB or trigger.

Power comes from an external 18 V adaptor. The case measures 477 x 264 x 78 mm, so plan the desk space before you buy.

What owners say

Owner feedback on UK retailer sites is consistent. People describe the sound as very faithful to the 909, the build as sturdy, and the sequencer as powerful while staying easy to follow.

The complaints are consistent too. Some functions sit behind button combinations instead of their own controls, and owners note Behringer has not fixed these in firmware. The knobs are packed close together, so a hand reaching for the snare tone can nudge a tom tuning. Muting the closed hat also mutes the open hat, which gets in the way of some live arrangements. A few owners who know the original well say the RD-9 lacks some of the TR-909's imperfections and feel.

Who should buy the RD-9

Buy it if you make house, techno or any style built on 909 sounds and want them from hardware, especially if you will use the individual outputs or sync it with modular gear. It also suits producers who want a deep step sequencer with probability and polymeter in a dedicated box.

Look elsewhere if desk space is tight (a smaller machine such as the RD-6 or a groovebox may suit you better), if you want realistic acoustic kits for practice (look at a sample-based machine like the Alesis SR-18), or if you want the exact sound and feel of an original 909 and can stretch to one.
