How does the UB-Xa MINI differ from the full-size UB-Xa?

It is a streamlined version: fewer keys, a smaller panel and a more travel-ready build, while keeping the analog engine, three VCOs and the 12/24 dB filter. The full-size model gives you a larger keyboard and more front-panel controls.

Yes. The signal path is fully analog, with three VCOs and an analog filter switchable between 12 and 24 dB slopes. The LFO and sequencer are there to modulate that analog engine.

How many voices does it have?

The UB-Xa MINI is a polyphonic synth, but it has fewer voices than the full-size UB-Xa. Check the voice count if you plan dense, sustained chords.

Can it save my sounds?

There are 10 memory slots tied to the 16-step motion sequencer, so you can store sequences and motion patterns. It is not a full patch-memory synth in the way larger polysynths are.

The synth itself with its 27 touch-sensitive keys and onboard sequencer. Check the listing for the power supply and any cables included.

Is it good for live use?

Yes, its compact size and knob-per-function layout suit stage work, and the motion sequencer covers grooves and evolving textures. The 27-key range is the main limit for two-handed playing.
