Behringer TD-3 Synthesizer Black

Analog Bass Synthesizer — Faithful TB-303 Recreation in Black

Built around the legendary Roland TB-303, the Behringer TD-3 Black is a monophonic analog bass synthesizer bringing Acid House-era squelch into a compact desktop chassis. Every oscillator, filter, and amplifier runs through genuine analog circuitry, capturing the warmth and unpredictability that made the original hardware iconic. Producers chasing that distinctive resonant bass voice will find this unit an accessible entry point into the 303 sound.

What Makes the TD-3 Black Stand Out

Every element of the TD-3 Black runs through genuine analog circuitry. Transistor wave-shaping and matched transistors reproduce the original 303's quirky behavior, including the happy accidents producers still chase today. A 16-voice Poly Chain links multiple units over MIDI for stacked bass textures a single TB-303 could never deliver.

Analog VCO and 4-Pole Filter — The Heart of the 303 Sound

The TD-3 Black's sound engine centers on a single analog VCO with switchable sawtooth and square waveforms. A 4-pole low-pass resonant filter with cut-off, resonance, envelope, decay, and accent shapes the tone, with a single EG envelope.

• Oscillator: Analog VCO with sawtooth and square waveforms
• Filter: 4-pole low-pass resonant with cut-off, resonance, envelope, decay, accent
• Envelope: EG — single envelope generator for filter and amplitude shaping

16-Step Sequencer and 13 Mini Keys for Hands-On Pattern Building

Inside the TD-3 Black, a 16-step sequencer spans 7 tracks with 250 user patterns. An arpeggiator adds movement to held notes, while 13 mini key buttons handle pitches, accents, slides, and rests in the original workflow.

• Sequencer: 16-step, 7-track with 250 user patterns
• Keys: 13 mini key buttons for direct pitch and step entry
• Controls: 11 knobs and 28 switches for real-time parameter access

USB, MIDI, and CV/Gate — Modern I/O for Hybrid Setups

Modern connectivity sets the TD-3 Black apart from vintage 303s. Full-size 5-pin DIN MIDI in/out, USB 2.0 Type B, and 3.5 mm CV/Gate jacks let this unit drop into modular rigs and computer-based studios.

• USB: Type B (USB 2.0)
• MIDI: 5-pin DIN in/out
• Outputs: 1/4" TRS line out + 3.5 mm headphone
• CV/Gate: 3.5 mm TS filter, FM, accent, slide, gate, CV, sync

Who Should Buy the Behringer TD-3 Black

The Behringer TD-3 Black is the right choice for electronic music producers, Acid House enthusiasts, and live performers who need genuine 303-style squelch in a portable package. Beginners will find the workflow approachable, while experienced producers get the same hands-on programming feel as the original hardware. Beatmakers adding melodic bass lines to a groovebox setup will appreciate the compact form.

The TB-303 Legacy and Behringer's Analog Revival

Released in the early 1980s alongside the TR-606 drum machine as a budget accompaniment tool, the Roland TB-303 failed commercially. Chicago and Acid House producers later discovered that pushing resonance, accent, and slide turned it into the squelchy bass voice that defined a genre. The TD-3 Black continues that legacy with a fully analog circuit, engineered in Italy.
