Arturia MicroBrute UFO Limited-edition Analog Monosynth

MicroBrute UFO delivers raw analog power with an extraterrestrial edge. Equipped with the iconic Steiner-Parker filter, a multi-waveform VCO, a patchable Mod Matrix, and flexible sequencer - discover the same massive brute sound, recast in space black with martian-green detailing.

Product Features:

Summon Extraterrestrial Analog Energy

The same pocket-sized powerhouse that earned a cult following, recast for deep-space missions. MicroBrute UFO Edition packs a full analog voice, patch-point control, and hands-on sequencing into one compact unit - perfect for desktops, studios and live rigs alike.

Brute Sound

From unruly basslines and piercing leads to wild, unstable harmonics - MicroBrute delivers a sound that’s raw, edgy, and unmistakably Brute.

100% Analog Power

Mix and shape waves with MicroBrute’s VCO and built-in modifiers, then sculpt your sound through the iconic Steiner-Parker filter and Brute Factor drive.

Patchable Mod Matrix

Forge your own signal path: patch modulation sources and destinations to sculpt wild, custom tones - or connect external gear for more creative control.

Patch the Unknown

Mini-jack patch cables (included) let you reroute envelopes, LFO, pitch and more in seconds. Cross-patch external gear, feed CV loops or jack straight into your modular for interplanetary modulation.

Link Up and Lift Off

USB-MIDI, DIN MIDI and CV/Gate play nicely with DAWs, drum machines and Eurorack. Route external audio through the brute filter, sync to clock, or let MicroBrute run your whole rig.

Command Your Sound

From gut-punch basslines to sci-fi bleeps, MicroBrute UFO Edition adapts to any sonic mission. Twist a knob for instant attitude, sketch a new sequence on the fly, or reroute the Mod Matrix for wild, custom modulation. No menus - just hands-on analog response that’s uniquely yours.

100% Analog Signal Path: pure VCO → Steiner-Parker filter → Brute Factor drive

Syncable LFO: 3 waveforms, tempo-sync or audio-rate for FM craziness

Step-sequencer: 8 patterns, up to 64 steps each, with rate & trigger modes

Unique VCO: Saw, Pulse & Triangle with Ultrasaw, PWM, Metalizer and a Sub-5th generator for huge tone

Steiner-Parker Multimode Filter: Low-, High- & Band-Pass with self-oscillating resonance

CV/Gate & Audio In/Out: process external signals and patch into modular rigs

Patchable Mod Matrix: route LFO, ENV or external CV anywhere; mini-jack cables in the box

Brute Factor: from subtle saturation to full intermodulation havoc

MIDI DIN + USB-MIDI: plug into any DAW or hardware setup, clock-sync, or use as a master keyboard

Get Hands On

MicroBrute UFO Edition is a synth for fearless sound designers. Push the Brute Factor into overdrive, fold waves with the Metalizer, and patch signals in ways no manual ever intended - pure, untamed analog expression.

A Closer Look

Explore MicroBrute UFO Edition, from the expression controls to back panel connections - built for bold analog adventures.

Oscillator and Modifiers: MicroBrute UFO's 100% analog VCO blends saw, pulse, and triangle waves, enhanced with unique built-in modifiers: Ultrasaw for huge width, Metalizer for complex harmonics, and a sub-oscillator that rattles the room.

Filter and Brute Factor: Shape your sound with the Steiner-Parker multimode filter, offering low-pass band-pass, and high-pass modes with resonance that pushes into self-oscillation. Brute Factor adds everything from subtle grit to full-blown intermodulation havoc.

Mod Matrix: The patch bay Mod Matrix lets you create custom modulation routes and connect MicroBrute to modular, semi-modular, and analog gear. Shape, animate, and expand your sound without menus - just patch and play.

LFO: Syncable LFO with three waveforms, tempo sync, and audio-rate operation for vibrato, wild modulation, or FM-style tones.

Envelope and Controls: Classic ADSR envelope for precise dynamic shaping. Glide, modulation wheel depth, and direct controls for expressive, hands-on performance.

Sequencer: Program up to eight patterns with 64 steps each. Adjustable rate and multiple trigger modes let you lock in tight grooves or explore evolving phrases.

CV/Gate: Pitch Out, Gate Out, and Gate In for easy integration with modular systems, analog synths, and sequencers.

Audio In/Out: Process external audio through the filter and Brute Factor, or send MicroBrute's raw analog tone into your mix via Line Out or headphone output.

MIDI In: Sync and control MicroBrute UFO from any DAW, hardware sequencer, or MIDI keyboard.

USB MIDI: Bi-directional USB provides full MIDI integration - automate parameters or use MicroBrute as a compact master keyboard.
