Behringer UB-Xa 16 voice Polyphonic Multi-Timbral Synthesizer

Tax included.

Embrace the legacy and make your mark on history with the UB-Xa from Behringer. More than just a homage of a classic synthesizer, they’ve made sure that the UB-Xa has all the bells, whistles and characteristics that came with synthesizers of the past, but not only that! It’s also filled to the brim with modern features such as velocity and after-touch, 512 user program memories and comprehensive MIDI implementation


  • Analog polyphonic synthesizer and authentic reproduction of classic OB-Xa including original factory patches

  • Vintage mode allows selection of 8 synthesizer signatures including OB-Xa, OB-8 and more

  • 16 voices with 2 VCOs per voice and oscillator sync mode

  • Multi-timbral capability allows splitting or layering 2 different sounds

  • VCOs and VCFs based on reproductions of original 3340 and 3320 semi conductor designs

  • Both VCOs generate sawtooth, triangle or square waveforms with variable pulse width

  • Selectable dual-slope 12/24 dB analog low-pass filter per voice with adjustable resonance

  • 61 semi-weighted full-size keys featuring poly after-touch and velocity sensitivity

  • Flexible 8-channel modulation matrix for dramatic expansion of sonic possibilities

  • Dual-layer arpeggiator and sequencer with real-time sequence transpose

  • Velocity and after-touch can be optionally used for more expressive performance

  • 2 dedicated LFOs with 7 waveform shapes for modulation of pulse width, oscillator pitch and filter cutoff frequency

  • 2 ADSR generators per voice for control of VCF and VCA

  • Stereo VCA per voice to allow control over voice/layer panning

  • 26 rotary controls give direct and real-time access to all important parameters

  • High-quality LCD Display with encoder for rapid parameter editing

  • Assignable preset recall switches for immediate program selection

  • Spring-loaded pitch and assignable modulation paddles provide total hands-on performance

  • 512 user program memories with “compare and match” feature to quickly match all analog controls to stored program values

  • Fully servo-balanced outputs for highest signal integrity

  • CV/pedal inputs for connection to expression pedals and footswitches

  • MIDI Polyphonic Expression (MPE) to enable multidimensional controllers and multiple parameters per note

  • Comprehensive MIDI implementation (including NRPN/CC control of all parameters and bulk load/save)
