Arturia MicroBrute UFO is a limited-edition monophonic analog synthesizer for producers and sound designers who want raw analog bass and lead sounds with hands-on control. It is the MicroBrute design in a matte black shell with green accents: one analog VCO with Ultrasaw, Metalizer and overtone sub-oscillator, a Steiner-Parker multimode filter, Brute Factor drive, a patchable Mod Matrix, an 8-pattern step sequencer and 25 mini keys.
The original MicroBrute sound and patch panel, back in a limited black and green edition with new knobs.
Overview
MicroBrute UFO keeps the circuit and feature set of Arturia's MicroBrute and changes the look: a space-black body with martian-green accents. Arturia also fitted new knobs, which reviewers note are meant to avoid the sticky feel older units developed.
The signal path is 100% analog. A single oscillator blends sawtooth, square and triangle waves and adds three shapers: Ultrasaw for a wide saw, Metalizer for hard harmonics and an overtone sub-oscillator that can sit an octave or a fifth below. That runs into a 2-pole Steiner-Parker filter with low pass, band pass and high pass modes and Brute Factor, a feedback drive that goes from light grit to heavy distortion.
There are no menus and no patch memory. Every control is on the panel, and the Mod Matrix lets you patch the LFO and envelope to destinations or bring in CV from modular gear. The step sequencer holds 8 patterns of up to 64 steps, and the synth syncs over MIDI, USB or CV.

How Is the MicroBrute UFO Different From the Original MicroBrute?
Inside it is the same synthesizer: same oscillator, Steiner-Parker filter, Brute Factor, Mod Matrix and sequencer. The differences are the matte black and green finish and the new knobs. Arturia sells it as a limited edition.
Who Is the MicroBrute UFO For?
It suits someone who wants a first analog synth they can learn by turning knobs, and producers who need a dedicated bass or lead voice on the desk. Modular users can patch it into a Eurorack rig through its CV inputs and outputs, and its audio input lets you run drums or other synths through the filter and Brute Factor.
How Does the MicroBrute UFO Connect to Other Gear?
It has a 5-pin MIDI input, USB for MIDI in and out, CV inputs on the Mod Matrix, CV outputs for pitch, envelope and LFO, and gate connections, so it can be played from a DAW, a hardware sequencer or a modular system. Audio leaves on a 1/4-inch output with a separate 1/8-inch headphone jack.
