Behringer UB-Xa D Polyphonic Desktop Synth

Full Description

Vintage sounds at your fingertips

The UB-Xa D boasts eight vintage modes, including the legendary OB-Xa and OB-8 signatures. This allows you to switch between classic synthesizer sounds effortlessly, providing authentic analog warmth and character for your music.

Versatile polyphonic capabilities

With 16 voices, each equipped with two VCOs, the UB-Xa D delivers rich, full sounds. Its multi-timbral capability lets you split or layer different sounds, offering flexibility for both live performances and studio productions.

Extensive modulation options

The 8-channel modulation matrix dramatically expands your sonic possibilities. You can modulate pulse width, oscillator pitch, and filter cutoff frequency using two dedicated LFOs with seven waveform shapes, enabling highly dynamic and evolving sounds.

Intuitive control and performance

The UB-Xa D features 26 rotary controls for real-time access to key parameters, a high-quality LCD display for rapid editing, and assignable preset recall switches for immediate program selection. Its comprehensive MIDI implementation, including MPE support, ensures seamless integration with your existing setup.
