UB-Xa D

The Behringer UB-Xa D is the compact desktop module version of the legendary UB-Xa synthesizer. It packs the same immense 16-voice, bi-timbral polyphonic analog engine into a convenient rack-mountable unit, making it perfect for producers and musicians who want the colossal sound of a classic 80s polysynth without the large footprint of a keyboard version. The UB-Xa D delivers the authentic warmth, power, and lushness of the original, from its dual-oscillator architecture to its iconic 4-pole filter, providing a true vintage analog experience with modern stability and control.

The UB-Xa D features a pure analog signal path with 32 authentic VCOs (two per voice), based on the classic 3340 design. Its sound is shaped by a versatile 4-pole resonant filter with selectable 12dB or 24dB/octave slopes. The bi-timbral capability allows you to play two different patches simultaneously, either layered or controlled via separate MIDI channels. It includes two LFOs, two ADSR envelope generators, and memory for 512 user patches. A crisp OLED display makes navigating and editing sounds straightforward. While it omits the keyboard, it retains all the sonic power and features comprehensive USB and MIDI connectivity, making it easy to control from your favorite master keyboard or DAW. It's the perfect way to inject that legendary, stadium-filling analog sound into a modern studio setup.
