Behringer UBXa mini
The Behringer UB‑Xa Mini is a compact analog synthesizer inspired by the larger UB‑Xa model. It delivers a rich analog sound in a small package, featuring a fully analog signal path and three VCOs. The synth captures the character of the classic Oberheim OB‑Xa with authentic VCO and VCF circuitry.
The mini version is smaller, more affordable, and simplified compared to the full UB‑Xa. It includes a range of play modes and a 16-step motion sequencer, making it ideal for enthusiasts, learners, or as supplementary gear in a studio or live setup.

- Dual-slope low-pass filter (VCF): Switchable between 12 dB and 24 dB slopes for different tonal shapes.
- Ring Modulator on square waves: Adds metallic, bell-like textures.
- Play modes: Poly, Unison, Octaves, Fifths, Ring Unison, Ring Poly.
- LFO (Low-Frequency Oscillator): Multiple waveforms for modulation of pitch, filter cutoff, and PWM.
- 16-step motion sequencer: Includes 10 memory slots for recording knob movements.
- Compact format: 27 touch-sensitive keys for portability.
- Connectivity: USB‑C (power/data), headphone/line output, sync in/out, MIDI IN (5‑pin DIN).
