Behringer UB-Xa Analog Polyphonic Synthesizer

Behringer UB-Xa is a remarkable homage to the classic OB‑Xa synthesizer, delivering authentic sound reproduction with original factory presets. This powerful instrument blends nostalgic analog aesthetics with modern functionality, making it an ideal tool for contemporary sound creators. Thanks to its unique sound architecture, the UB‑Xa provides rich, dynamic audio material that can be freely modified to suit individual artistic needs.

Product Features

The main strength of this synthesizer is its 16‑voice polyphony, allowing full chord play without voice loss. Each voice is equipped with 2 analog VCO oscillators, providing a wide palette of tones. The device features a switchable 12/24 dB analog filter per voice, offering complete control over resonance and sound character. Additionally, the 61‑key keyboard with poly aftertouch and velocity sensitivity guarantees the highest level of expression while playing.

Professional Capabilities for Your Creativity

Behringer UB‑Xa is more than a synthesizer; it’s a comprehensive sound hub. The built‑in Vintage Mode lets you choose from 8 distinct synth signatures, including the iconic OB‑Xa and OB‑8, enabling quick adjustment of tonal character for any musical project. The multi‑layered modulator with 8 channels allows creation of complex modulation sequences, opening doors to limitless sound‑design creativity. Two dedicated LFOs with 7 wave shapes inject vitality and motion into every sound, eliminating the mechanical feel of digital production.

A flexible sequencer and arpeggiator with dual layers lets you craft intricate bass lines and melodies in real time. This tool not only reproduces sound but also inspires the creation of new musical layers. The ability to record and play back sequences makes the UB‑Xa ideal for both studio work and live improvisation. Its analog character delivers warmth and natural instability missing from virtual instruments, essential for professional music production.
