Behringer TD-3 Sintetizador Yellow

Behringer TD-3 Yellow — Analog Acid Bass Line Synthesizer

The Behringer TD-3 Yellow is a desktop analog bass synthesizer and sequencer, reviving the unmistakable squelch of the Roland TB-303 for modern creators. Its all-analog signal path features dedicated VCO, VCF, and VCA stages, producing the pulsing rhythms and greasy bass tones central to acid house and techno.

What Sets the TD-3 Yellow Apart from Other 303 Clones

Integrated distortion and tone control distinguish this model from most TB-303 recreations—a feature missing on the original Roland. Up to 16 units can be daisy-chained via Poly Chain, achieving 16-voice polyphony, while Synth Tool editor software enables USB pattern streaming.

Analog Voice Architecture for Punchy Bass and Squelchy Leads

Every audio stage remains in the analog domain, providing warmth and grit that digital emulations rarely match. The single analog VCO offers both sawtooth and square waveforms, with an LFO available for subtle modulation. A four-pole resonant lowpass filter sculpts the sound from clean to aggressive.

• Oscillators: Analog VCO with switchable sawtooth and square waveforms — the heart of classic acid bass lines
• Shaping the tonal envelope is the four-pole resonant lowpass VCF with adjustable envelope and decay, ensuring broad sound design possibilities.
• Adding grit and aggression, the built-in distortion with tone control sets this unit apart from the original TB-303

Pattern Programming and Real-Time Control

Composing and storing bass lines happens entirely onboard—no computer required. Step mode and Keyboard mode allow different workflow options, and an arpeggiator expands generative possibilities. Players can use programmable accents and slides, though pitch bend, modulation wheel, and aftertouch are not included.

• Sequencer: 16-step, 7-track — enables both step and real-time keyboard recording
• Pattern Memory: 250 user pattern slots — store enough material for extensive live sets
• Live entry is intuitive thanks to the touch-style keyboard with 13 mini key buttons

Studio and Stage Integration in a Compact Desktop Chassis

Despite a small footprint, the desktop module is designed for both studio and live use, with versatile MIDI, USB, and analog sync connectivity options.

• MIDI: USB-MIDI and 5-pin DIN In/Out/Thru — works seamlessly with any DAW or hardware configuration
• Poly Chain: Daisy-chain up to 16 units for 16-voice polyphony in larger setups
• Measuring 56 × 305 × 165 mm and weighing 0.8 kg, it fits easily on any desktop synth stand

Built for Acid House Producers, Techno Performers, and Hardware Enthusiasts

Electronic music producers needing classic acid bass at an accessible price will find this instrument ideal. The TD-3 Yellow fits live techno and house sets relying on hardware, as well as sound designers exploring squelchy textures and home producers wanting the TB-303 workflow without the cost of vintage gear.

Behringer and the TD-3 — Affordable Homage to a Legend

Behringer, founded in Germany by Uli Behringer, has become one of the world's leading manufacturers of affordable music equipment. The TD-3 series, introduced in February 2020, is a tribute to the Roland TB-303—a synth launched in 1981 that unexpectedly shaped the sound of acid house.
