Compact, expressive and affordable, the
Behringer UB-Xa MINI captures the spirit of legendary 80s analog synthesizers in a mini format designed for modern creativity. This
paraphonic analog synthesizer faithfully reproduces the sound architecture of the iconic Oberheim OB-Xa, while offering an intuitive workflow and extended modulation possibilities. Ideal for mobile musicians, producers or vintage sound enthusiasts.
Authentic analog sound, inspired by the classics
The UB-Xa MINI features a true
100% analog signal path, based on VCO, VCF and VCA circuits recreated from original schematics. Its
3 analog oscillators (saw and square waveforms) deliver a warm, lively tone characteristic of vintage synthesizers. Unlike a fully polyphonic model, this synth is
3-voice paraphonic: the three oscillators can play different pitches but share the same filter and amplifier. This allows for simple chords and dense textures while maintaining analog coherence. Its
switchable 12 / 24 dB low-pass filter with adjustable resonance sculpts the tone precisely, while a built-in
ring modulator adds metallic or grainy timbres perfect for percussive or experimental sounds.
A compact, creative and inspiring format
With its
27 velocity-sensitive keys and intuitive layout, the UB-Xa MINI offers excellent playability despite its small size. Several
play modes allow for varied textures: unison, octaves, fifths, ring unison or ring poly. The
syncable LFO (4 waveforms) modulates pitch, filter cutoff or pulse width to bring the sound to life. Its
16-step sequencer with
10 memory slots and motion recording lets you create evolving patterns, hypnotic basslines or rhythmic textures. Thanks to its USB-C power supply, it easily connects to a computer, MIDI controller or mobile performance setup. It’s an instrument designed for sonic experimentation, live performance and creative sessions where inspiration must flow freely.
Who is it for?
The Behringer UB-Xa MINI is aimed at
musicians curious about analog synthesis, whether beginners, beatmakers or experienced producers. Its paraphonic architecture allows exploration of analog harmonic richness without the complexity or cost of a traditional polyphonic synth. It’s also a great choice for live performers or mobile creators seeking a compact and inspiring instrument.
Usage tip
Although presented as a “polyphonic” synth, it is in fact a
3-voice paraphonic model. Each oscillator can be tuned independently, but all pass through the same VCF/VCA: ideal for expressive leads, thick basses and textured chords. This paraphonic behavior, typical of vintage synths, gives the UB-Xa MINI a unique sonic identity, halfway between mono and polyphony.
