Arturia MicroBrute UFO Analog Monophonic Synthesizer - Limited Edition

Introducing MicroBrute UFO, a special-edition version of the iconic compact analog monosynth. Designed for musicians who crave hands-on analog power in a small, affordable package, the MicroBrute UFO delivers raw sonic potential with a unique design twist and the same fierce sound that made it a modern classic.

Uncompromising Analog Power, Reimagined

For musicians and producers seeking a compact, affordable analog synthesizer with real hands-on control, MicroBrute is a pure analog powerhouse that punches above its size. It features a 100% analog signal path, delivering warm, raw tones without digital oscillators or DSP. At its core is a single VCO with Ultrasaw, Metalizer, and Overtone controls, capable of creating complex, layered sounds. The Steiner-Parker multimode filter provides low-, high-, and band-pass shaping, while Brute Factor adds aggressive saturation and feedback. With a built-in 64-step sequencer and a patchable CV/Gate matrix, MicroBrute offers semi-modular flexibility and seamless modular integration—no computer needed.

Built for Explorers of Analog Sound

Whether you're a beginner exploring synthesis or a seasoned artist building a modular rig, MicroBrute UFO offers a true analog experience with a small footprint and pro-grade features. Every function is directly accessible from the panel—no menus, no presets, just pure sonic creativity.

MicroBrute was built to answer a clear need in the synth world: a simple, powerful, and compact analog instrument that doesn’t compromise on character. With a full modulation matrix, sequencer, and classic analog signal path, it stands out in a sea of over-complicated or digital-first synthesizers.

Deep Sound Design Capabilities:

Find the Right Waveform - Shapers & Volume

Many timbres can be built with MicroBrute's Waveform Shapers. On top of that, the Waveform Mixer can easily saturate so as you bring up waveforms they start to interact in unique ways. Explore the synergies between Shapers and Mixer.

Feedback, Twice

Drive the Steiner-Parker Resonance to the edge to make it self-oscillate. Crank up the Brute Factor to introduce analog feedback-like saturation, turning clean tones into raw, distorted growls full of character and punch.

Both introduce feedback. Explore how they interact together in Low-Pass, Band-Pass and High-Pass modes.

Modulate Internally, Externally

Use the patchbay to route internal signals like LFOs or envelopes as well as any external CV source to destinations such as pitch, filter cutoff, or Metalizer. Send or receive pitch and gate signals to and from other analog gear or modular synths.

Destroy External Audio

Run other instruments, vocals, or drum machines through MicroBrute’s filter and Brute Factor to inject analog character and distortion into any external source. A MicroFreak into a MicroBrute is a dangerous digital / analog synth combo.

A Synth Designed to Be Played

Despite its compact size, the 25-key keyboard combined with octave shift buttons lets you play across a full range of notes, great for basslines, melodies, or solos. Perform real-time changes with the pitch bend and mod wheel, assign modulation to different destinations for dynamic, expressive play.
