The Behringer BDS-3 is a modern analog recreation of the iconic Simmons SDS-3 drum synthesizer from the late 1970s, famous for its distinctive electronic percussion sounds in 80s music and new wave. This standalone/desktop module (with full Eurorack compatibility in 70 HP format) features four identical, fully independent analog drum channels plus a dedicated special effects channel, delivering punchy, synthetic toms, bass drums, snares, cymbals, bells, gongs, vibes, and beyond through self-oscillating diode ladder filters, white noise sources, pitch bend envelopes, and extensive controls. With MIDI In/Thru, USB, individual outs per channel, main mix out, and trigger inputs, it’s perfect for classic Simmons-style kits, experimental percussion, or integration into modular rigs as a powerful analog drum voice or voice expander.

Key Features & Signal Flow
- Four independent analog channels — Each recreates the SDS-3’s signature sound with diode ladder self-oscillation for resonant, punchy hits; tune for kicks, toms (with pitch sweeps), snares, cymbals, or metallic percussion.
- Special effects channel — Extra voice for bells, gongs, vibes, or experimental tones—expand your kit without extra modules.
- Pitch bend envelopes — Up/down sweeps per channel for classic Simmons “pitch drop” toms or rising hits; adjustable direction and amount.
- Impact click & decay controls — Shape attack transients and tail lengths for tight or ringing percussion.
- MIDI & trigger flexibility — Play via MIDI keyboard/sequencer (polyphonic potential across channels) or modular triggers; USB MIDI for DAW integration.
- Individual outputs — Route each channel to separate effects, mixers, or processing chains for multitrack recording or spatial effects.
- Eurorack integration — Mount in a 70 HP case for full modular use; patch triggers from sequencers, modulate parameters externally if CV accessible.
- Classic 70s/80s analog character — Raw, synthetic drum tones with warmth and grit—far from sample-based machines; infinite sound design for unique kits.
- Expressive controls — Pedal inputs for real-time pitch/decay manipulation; LFO/S&H for modulated chaos.
