Behringer UB-Xa Mini Analog Synthesizer

The Behringer UB-Xa Mini is a portable analog polyphonic synthesizer that brings the iconic OB-Xa sound into a smaller, more accessible format. With three rich VCOs, a pure analog signal path, and a switchable 12/24 dB low-pass filter, it delivers the lush pads, brassy leads, and punchy basses that defined the golden era of analog synthesis.

Whether you’re producing in the studio or performing on stage, the UB-Xa Minis hands-on controls and expressive touch keys offer a responsive and inspiring creative experience.

Designed for musicians on the move, the UB-Xa Mini distills the power of the full-size UB-Xa into a compact desktop format. With three analog oscillators, a motion sequencer, and multi-mode ring modulation, it opens the door to endless sound design possibilities from warm vintage tones to futuristic textures.

Its 27 touch-sensitive keys make for fluid and expressive playability, while the motion sequencer and multi-mode ring modulator inspire evolving, dynamic performances. The built-in Behringer SynthTribe software offers seamless integration for patch management and updates, making this synth as practical as it is powerful.
