ARTURIA - MICROBRUTEUFO - MicroBrute UFO Edition - 25-key Synthesizer

MicroBrute UFO Edition: 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.

Summon the 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.

From sub-weight basses and razor leads to acidic sequences and cinematic drones - all from one powerful oscillator, a classic filter, and a few smart modifiers.

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


Oscillator:
That punches above its weight
MicroBrute’s single analog oscillator is anything but basic. With waveform mixing, built-in wave shaping, and a powerful sub control, it delivers the kind of raw, versatile tone you’d expect from synths three times the size.

Blend saw, square, and triangle waves in variable amounts—not just on/off switches. Add bite and variation with Ultrasaw, Metalizer, and pulse width controls.

Overtone:
A redesigned sub-oscillator adds thickened lows and complex harmonics. Push it further for 5th-up intervals and modulate it via the Matrix for gritty, expressive tones.

Ultrasaw:
Thickens the saw wave with phase-shifted layers. Modulate it with the LFO to simulate detuned multi-oscillator stacks.

Metalizer:
Twists the triangle wave into jagged, harmonic-rich shapes. Route the envelope for dynamic sweeps, growls, or tearing leads.

Modulation Beast:
MicroBrute’s modulation goes far beyond the basics
With a full LFO, ADSR envelope, and patchable Mod Matrix, you can shape pitch, filter, Metalizer, and more. Default routings like LFO to pitch and envelope to Metalizer get you started fast, while the mod wheel puts vibrato and filter sweeps at your fingertips.

Override defaults, patch your own routes, or connect to modular gear for external control. Whether you’re after subtle movement or wild, evolving modulation, MicroBrute gives you direct, hands-on flexibility.

Sequencer details:
MicroBrute’s step sequencer combines hands-on control with powerful customization. Build patterns, tweak playback, switch sequences on the fly, and go deeper when you need it.
8 patterns
Record up to 8 sequences, each up to 64 steps, and store them safely in internal memory.

Input notes one by one, tap in rests, and switch between patterns instantly or after the current one finishes.

Multiple Modes:
Trigger sequences manually or let them loop automatically with Note On and Continuous Play modes.

Use the companion software to adjust step length, sync behavior, and trigger logic to match your setup.

Import/Export:
Use the free editor to back up, reload, or swap sequences via USB.

Keep your grooves archived and ready—whether for live shows or sound design sessions.

Essential I/O:
Whether you're syncing hardware, processing audio, or jamming with your DAW, MicroBrute keeps your setup connected.
Play an entire set, compose an entire soundtrack from start to finish. Or, connect to your existing rig for a seamless musical experience.

CV/Gate:
Standard 1V/oct CV/Gate makes MicroBrute a great addition to modular rigs. Use its sequencer, envelope, and LFO to control other synths—or let them control the Brute.

Audio IN:
Run external audio through MicroBrute’s filter and Brute Factor™ for gritty shaping and rhythmic modulation. Great for vocals, drum machines, or anything that needs a twist.

MIDI/USB:
Full MIDI I/O via USB and DIN lets you sequence, sync, and play from any controller. MicroBrute fits just as easily into a DAW setup as it does into a hardware jam.
