Behringer RD-8 MKII Rumpukone/Groovebox

Analog Drum Machine with Authentic 808 Character

The Behringer RD-8 MKII is an analog drum machine built around a reproduction of the long-discontinued V662 OTA chip, the same component that gave the original TR-808 its unmistakable sonic fingerprint. Sixteen analog-generated voices cover the full classic palette, from the deep, dark bass drum to the sizzling open hi-hat and the instantly recognizable cowbell. Eleven simultaneous voices (twelve when the global accent is engaged) can be routed through eleven independent 1/4" TS outputs, letting producers record and process each instrument on its own channel. The Behringer RD-8 MKII is the right choice for producers who want genuine analog 808 character without paying vintage hardware prices.

Modern Sequencer and Sound-Shaping Tools

What sets this second-generation unit apart from earlier clones is the depth of its performance-oriented sequencer and the addition of a built-in effects bus. The 64-step sequencer supports polyrhythms, step repeat, note repeat, real-time triggering, track mute, and track solo, while an encoder provides real-time control over tempo, swing, probability, flam, and random variation for a more human feel. Pattern Mode chains patterns into songs, Song Mode chains songs into full sets, and an Auto-Fill function generates variations on demand.

Sequencer and Pattern Architecture

The sequencer is the heart of any drum machine workflow, and the RD-8 MKII gives producers serious depth without sacrificing immediacy. Patterns can be saved, copied, erased, and dumped, while the Auto-Scroll function lets users navigate long arrangements hands-free.

• Sequencer Steps: 64 steps — long enough for polyrhythms and evolving grooves, short enough to stay punchy.
• Pattern Storage: 256 patterns across 16 songs — enough headroom for full live sets and studio sessions.
• Pattern Mode: up to 99 iterations per pattern part — useful for extended builds and breakdowns.

Analog Sound Generation and Voice Architecture

All sixteen voices are generated in the analog domain, giving every hit the warmth, snap, and movement that digital emulations struggle to replicate. The reproduction V662 OTA chip is central to the bass drum and several other voices, restoring the harmonic character that defined countless hip-hop, electro, and techno records.

• Sound Chip: V662 OTA reproduction — recreates the original 808 voicing circuit for vintage authenticity.
• Number of Sounds: 16 analog voices — bass drum, snare, three congas, three toms, claves, rimshot, maracas, clap, cowbell, cymbal, closed and open hi-hat.
• Simultaneous Voices: 11 (12 with global accent) — enough headroom for dense, layered patterns.

Connectivity, Filter, and Effects Bus

Eleven individual outputs, full MIDI implementation, USB, and trigger outs make the RD-8 MKII a flexible hub in any hybrid setup. The integrated Wave Designer and dual-mode analog filter add per-voice sound shaping that the original 808 never had.

• Analog Filter: state-variable, 12 dB slope, switchable LPF/HPF with cutoff from 10 Hz to 15 kHz and resonance from 0 to 10.
• Wave Designer: Attack -15 to +15 dB, Sustain -24 to +24 dB — assignable per voice across the 11-voice bus.
• Outputs: 11 x 1/4" TS voice outs, 1 x 1/4" TRS main out, 1 x 1/4" TRS phones — plus MIDI In/Out/Thru, USB Type-B, 3 trigger outs (+5V, 1 ms pulse), and clock in/out.
• Dimensions: 77 x 498 x 265 mm — Weight: 3.0 kg — desktop form factor that sits comfortably above a keyboard or beside a mixer.

Who Is the Behringer RD-8 MKII For?

Beat makers producing hip-hop, trap, electro, techno, house, and lo-fi will find the RD-8 MKII's classic 808 voicing immediately useful, while the per-voice outputs invite more elaborate mixing and outboard processing workflows. Live performers benefit from Song Mode chaining, Auto-Fill variations, and the ability to switch songs without interrupting playback, making the unit a reliable stage companion. Sound designers and modular users can integrate the RD-8 MKII via MIDI, USB, clock, or the three +5V trigger outputs, syncing it to Eurorack setups or DAW sessions. The Behringer RD-8 MKII is the right choice for producers and performers who need authentic analog 808 sounds, deep sequencing, and modern connectivity in a single desktop unit.

Behringer and the Rebirth of a Legend

Behringer was founded in Germany by Uli Behringer and has built its reputation on affordable, high-value equipment since the release of the Studio Exciter F. Through acquisitions of Midas, Klark Teknik, and TC Electronic, the company folded professional audio expertise into its product development pipeline. The RD-8 MKII continues that philosophy by reviving a now priceless vintage icon at a price within reach of home studios and small project rooms. Its optimized circuit design, with an improved signal-to-noise ratio and refined phase response on every output, marks a clear step forward from the first-generation RD-8.
