Arturia MICROBRUTE UFO Limited-Edition Analog Synthesizer

The Arturia MICROBRUTE UFO is a limited-edition monophonic analog synthesizer designed for hands-on sound creation in compact studio, live, and hardware-based music setups. It combines a 25-note mini keyboard, onboard step sequencer, and patchable modulation system in a portable desktop format. The UFO edition retains the original MicroBrute architecture while adding a space-black finish with martian-green detailing.

This synthesizer is suited to musicians who want direct control of basses, leads, percussion, sequences, and experimental textures without navigating menus. Its fully analog audio signal path centers on a voltage-controlled oscillator and a Steiner-Parker multimode filter. Front-panel controls allow sounds to be shaped quickly during writing, recording, or performance.

The oscillator section blends sawtooth, pulse, triangle, and overtone waveforms, with PWM, Ultrasaw, Metalizer, and overtone controls for expanding the harmonic character. The Steiner-Parker filter offers low-pass, band-pass, and high-pass modes, while resonance can reach self-oscillation. Brute Factor adds internally routed feedback for adjustable saturation and more complex harmonic response.

A patchable Mod Matrix lets users route the LFO, envelope, keyboard CV, and external control voltages to sound-shaping destinations. The LFO provides three waveforms and can run freely or synchronize with the sequencer. A dedicated ADSR envelope, keyboard tracking, glide, pitch wheel, and assignable modulation wheel support expressive performance control.

MICROBRUTE UFO can serve as a compact standalone instrument or integrate with computers, MIDI hardware, analog synths, and modular-compatible gear. Its sequencer stores eight patterns with up to 64 steps each, and USB MIDI supports communication with a computer and Arturia's editing software. Audio input, line output, headphone output, MIDI input, and CV/Gate connections make it practical for expanding an existing music-production setup.

Key Features

• Multi-Waveform VCO: Blends saw, pulse, triangle, and overtone oscillator sources.
• Patchable Mod Matrix: Routes internal or external modulation without menu-based programming.
• 64-Step Sequencer: Stores eight playable patterns for repeatable musical phrases.
• MIDI and CV Integration: Connects with DAWs, MIDI devices, and analog gear.

Design & Installation

The MICROBRUTE UFO uses a compact desktop chassis with a steel bottom panel, 25 mini keys, tactile knobs, sliders, patch points, and a limited-edition space-black and martian-green exterior. Its control layout places oscillator, filter, modulation, envelope, and sequencing functions on the front panel for immediate adjustment. The unit measures 60 x 325 x 221 mm and weighs 1.75 kg.

Place the synthesizer on a stable desktop, keyboard stand shelf, or performance surface, then connect the included 12V DC, 1A center-positive power supply. Connect its 1/4-inch line output to a mixer, audio interface, or amplifier, or use the 1/8-inch headphone output for personal monitoring. USB MIDI, DIN MIDI input, and 1V/oct CV/Gate connections support integration with computer-based and analog hardware systems; the rear audio input is line level, so microphones and guitars require a suitable preamp.
