MiniBrute was built to offer great analog sound with a very easy-to-use interface, without compromising quality. The result of fine R&D and skilled craftsmanship. A 100% Analog audio signal path, delivering huge bass lines, screaming leads, outstanding arpeggios and wild effects.

Analog synthesizers of yesteryear are highly sought-after on the “used” market for their warmth, fatness, slight instability, and their unmistakable sonic character. Digital synths sometimes offer more possibilities, but can sound a bit sterile at times and lose musicians in endless menus and boring sound design concepts.

MiniBrute makes a bold entrance, standing proudly among legendary analog machines like the MiniMg, Pro-One, SH-101, MS-20, and Odyssey. MiniBrute offers the classic analog sounds of the most iconic recordings, while making a mark of its own with unique features and some serious attitude.

So what does MiniBrute sound like?

MiniBrute was designed with one thought in mind: produce amazing analog sounds. And it hits the target dead-center, serving up powerful basses, hypnotic drones, screaming leads, acid sequences, ethereal monopads, 80’s arpeggios, mind-blowing effects and fascinating sonic experiments.

If you’re looking for deep funky basses, mellow leads, clavinets or woodwind-like sounds, MiniBrute can produce those too. But the beast that lurks within is always waiting for you to twist that knob.

Your Sounds, Your Attitude

MiniBrute doesn’t have presets. You yourself will build every sound you hear. That may seem strange, but take it from us: it’s fun, it’s creative and it’s an organic approach to making music. Plus it’s easier than browsing sub-menus! But you can still play sounds made by other programmers. And you can store your own sounds. How does that work?

Because we provide preset sheets that fit over the MiniBrute controls. Dial in the values on those sheets and you’ll recreate a sound in one minute. And your sounds can be preserved the same way: make a few marks on a blank sheet and you’re done.

Steiner-Parker Filter

MiniBrute incorporates the legendary Steiner-Parker multimode filter. Introduced for the first time in the Synthacon synthesizer back in the 70’s, this marvelous filter not only has a Low pass mode like other designs, but also Band pass, High pass and Notch positions, making it a highly-versatile and acclaimed boutique filter.

The MiniBrute filter is based on the core of this legendary filter, and it has been enhanced to deliver an even wider range of cutoff and resonance. Nyle Steiner himself has verified and approved these enhancements.

Teamed with the MiniBrute’s multi-wave oscillator and its wide modulation capabilities, the Steiner-Parker filter adds an extremely versatile and aggressive edge that will make your sound stand out.


No, there’s no DCO… there’s nothing digital at all in MiniBrute, only a pure VCO (Voltage Controlled Oscillator) for absolute authenticity. MiniBrute’s VCO is classic in its sound and modern in its design, providing 4 simultaneous waveshapes that can be individually mixed with white noise and the external audio input. There’s also a sub-oscillator and several analog signal enhancers such as Metalizer and Ultrasaw, all of which makes for custom waveshapes that no other analog hardware synthesizer can match.

Sub Osc

MiniBrute’s sub-oscillator will generate a sine or square wave as much as two octaves down. It's ready to rattle the house at your command.


Ultrasaw provides shimmering sawtooth waveforms that will considerably enrich the sound.

It basically makes two phase-shifted copies of the raw sawtooth waveform. The copies have ever-evolving phase shifts of their own, and when mixed with the original sawtooth they complement one another.

This results in a lively, rich, bright ensemble effect that can be further enhanced by the modulation rates of the phase-shifted copies. This is the first time a feature like this has been offered in an analog keyboard.


The Metalizer takes the basic triangle waveform, “warping” and “folding” it to create complex, jagged waveforms that are rich in high harmonics. This results in pitched, “metallic” sounds that are ideal for harpsichord- and clavinet-type tones. Dynamic modulation of the warp/fold parameters by an LFO or envelope opens up a realm of “clangorous” sounds that will cut through your mix nicely.

Brute Factor™

Brute Factor™ was inspired by a patch made on a famous vintage synthesizer by connecting its headphone output to the external audio input. The result was a type of feedback loop that’s ideal for raspy and grungy sounds. This technique has been adapted and implemented internally in the MiniBrute.

At low Brute Factor™ settings the distortion is smooth and gentle, but it becomes harsher as you turn up the knob. When the level exceeds 75% of maximum the MiniBrute can go berserk and produce barely controllable, crazy feedback sounds.

Modulations Galore

Modulations are the key to widening a synthesizer’s sound palette. While many synths offer too few options and, in the end, a limited range of sounds, MiniBrute opens the door to a world of combinations that will allow you to create a unique and original sonic signature.

The LFO1 waveforms include sine, triangle, sawtooth, square, random square and random sine waves. The modulation amounts are bipolar and can be routed to 4 destinations: PWM & Metalizer, Pitch, Filter, and Amplifier. So you can really get creative and start modulating the Filter with a negative slope, for example, while increasing the Pitch.

Two full ADSR (Attack, Decay, Sustain, Release) envelopes are available on MiniBrute, one for controlling the Filter and the other controlling Volume (Amplifier). The Filter envelope can also modulate the Pulse Width of the Square wave and the Metalizer amount. Use the Fast/Slow switch to select ultrafast, 1 millisecond responses for snappy electro basses and leads, or responses that can exceed 10 seconds for slow, evolving soundscapes.

Thanks to its full MIDI/CV/USB connectivity, MiniBrute is designed to fit seamlessly in any modern or vintage studio.

MIDI In/Out:

Use MiniBrute as a master keyboard or a MIDI sound source for your DAW or any other MIDI gear you have. Synchronize MiniBrute's Arpeggiator with an incoming MIDI clock and play in perfect sync with external drum machines, computers, or other MIDI equipment. LFO1 can also lock to the Arpeggiator, allowing for rhythmic Filter, Pitch and Amp modulations that are always in sync.

USB In/Out:

Sequence MiniBrute directly from your computer’s DAW without the need for a separate MIDI interface. MiniBrute can also serve as a USB MIDI controller and as a USB MIDI-to-CV converter: it will translate incoming USB and MIDI data into CV Pitch Out and Gate Out signals, making it a great way to control vintage synths from your computer or MIDI interface.

CV In/Out :

Chain MiniBrute to your vintage or modular synthesizer to get a beefier sound. Control and sequence MiniBrute from your vintage equipment, or use MiniBrute to control your vintage synths (it conforms to the classic 1 Volt per Octave scaling system). You can also use MiniBrute as a MIDI-to-CV converter.

Audio In:

Process any external sound through MiniBrute’s filter, VCA and Brute Factor™ circuit. MiniBrute can be used as an analog powerhouse for adding warmth, grit and filter effects to drums, guitars, vocals, and more. It will alternatively generate automatic bass lines from percussive sounds by switching the Gate source selector to audio.

MiniBrute can also be used as a MIDI-to-CV/Gate converter, establishing a link between your computer-based studio and your vintage gear.

Total Control

MiniBrute features a full set of 29 high-precision knobs, 14 metal sliders and 8 metal switches that offer direct control over your sound.
Don't worry; MiniBrute has a much faster learning curve than any of your digital equipment. You’ll find that every control on MiniBrute is laid out in a very intuitive manner.

You want to make it brighter? Grab the Cutoff knob and turn it up. You want to make it fatter? Grab the Sub Osc slider and move it up. You want your sound to grow fangs and snarl like a beast?
