Add a little acid to the mix. The Behringer TD-3 is a 303-style analog bass line synthesizer, basing its design on an iconic synth that shaped the sound of Acid House and EDM. The TD-3 Synthesizer brings a vintage synthesizer into the modern era. This compact and highly portable bass synth faithfully recreates the original circuitry with a pure analog signal path. It comes jam-packed with onboard controls including a 16-step sequencer with up to 250 user patterns. The original was known for its unique squelching-style bass sounds, which were instrumental in forming the sound of popular dance music. The TD-3 features the same unique 4-pole low-pass resonant filter and distortion circuitry that made the original so versatile. This new and improved design retains the same sound and controls as the original, with the addition of MIDI and USB connectivity for modern music production.
