Analog Monophonic Bass Synthesizer Behringer TD-3-MO-BK — 303-style, monophonic analogue bass synth, black

The Behringer TD-3-MO-BK is an analog monophonic bass synthesizer modelled on the classic 303 architecture. It provides a single-voice analogue signal path intended for basslines and acid-style leads, with hands-on controls for shaping filter, envelope, accent and slide. Compact and finished in black, the unit is designed for studio production and live electronic performance where a focused, raw analogue bass sound is required.

Advantages

The TD-3-MO-BK offers an authentic analogue tone with simple, tactile controls that let you shape resonance, cutoff and envelope intensity in real time. Its monophonic design concentrates circuitry on a single voice for pronounced low-end response and character. The compact footprint and robust build make it suitable for stage use and tight studio setups while its sequence-friendly interface supports dynamic bass patterns and acid-style modulation without complex menus.

Suitable for

• Creating basslines for electronic, techno and house productions
• Performing live acid-style sequences and leads
• Integrating into small studio rigs as a dedicated analogue bass source
• Hands-on sound design and real-time modulation during sets

Key specifications

• Monophonic analogue signal path optimized for bass frequencies
• Dedicated controls for filter cutoff, resonance, envelope intensity and decay
• Accent and slide controls for dynamic sequencing
• On-board step sequencer for pattern creation and live manipulation
• Compact, stage-ready chassis with front-panel tactile knobs and switches

How to use

Connect the TD-3-MO-BK to your mixer or audio interface using its audio output and set levels to avoid clipping. Use the step sequencer to program bass patterns, adjusting accent and slide to introduce rhythmic and pitch variation. Sculpt the tone with cutoff and resonance controls, and use envelope parameters to adjust how the filter responds over time. For live performance, lock in a sequence and tweak controls in real time to create evolving acid-style lines.

Recommendations

Use the TD-3-MO-BK with a clean preamp or DI to preserve its analogue character. When integrating with other gear, synchronize the sequencer clock to external gear for tight timing, and apply moderate resonance boosts to avoid excessive distortion at high volume levels.
