Takes your sound
to a new level

Over a decade on, MicroBrute’s fierce analog character continues to stand out.

With a 100% pure analog signal path, hands-on control, and flexible connectivity via MIDI, USB, and CV/GATE, this small but mighty synth is as relevant as ever, while staying true to its sonic roots.

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.

VCO

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.

Audio
Processor

MicroBrute is more than a synthesizer.

MicroBrute is more than just a synth—it’s a powerful sound-shaping tool. Plug in external signals like vocals, guitars, or other synths and run them through the filter, Brute Factor™, and final output stage.

An audio input and rear trim pot give you precise level control. Whether you're shaping drums or mangling loops, MicroBrute lets you process sound creatively and destructively.

Steiner-Parker
Filter

So what does MicroBrute sound like?

At the heart of MicroBrute is the legendary Steiner-Parker multimode filter, offering low-pass, band-pass, and high-pass modes for flexible tonal shaping.

This isn’t a watered-down replica—Nyle Steiner approved this design himself. It’s a boutique-grade analog filter with deep character and wide-ranging control over resonance and cutoff.

Brute
Factor™

The Brute Factor™ was inspired by a patch made on a famous vintage synthesizer.

Brute Factor™ emulates a classic feedback patch by internally routing the output back into the signal path—perfect for adding grit, saturation, or total chaos.

Dial it low for extra warmth or crank it past 65% for wild, barely-controllable feedback. It’s aggressive, unstable, and one of MicroBrute’s signature moves.

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.
