Arturia MicroBrute 25-Key Analog Synthesizer
The Arturia MicroBrute 25-Key Analog Synthesizer is possibly the most powerful pound for pound analog synth available! Arturia packs the MicroBrute with mixable waveforms, a new sub oscillator design, famous Steiner-Parker multimode filter, super fast envelope, syncable LFO, a step sequencer, patchable mod matrix and more. With a 100 percent pure analog path and interconnectablity via MIDI, USB, CV/GATE, the MicroBrute is a true powerhouse synth.
No presets, no menus, nothing to get between you and the ability to sculpt your sound live. Not only does Arturia’s MicroBrute give you the means to create, perform and be completely original every time you power up, it does so with astounding sound quality.

The VCO on the MicroBrute synth is unique in the synthesizer world. It features the ability to mix waveforms in variable amounts as opposed to simple ON/OFF switches that are found on many synths at four times the price. The sound possibilities don’t stop there. Each waveform has wave modifiers that allow even further tonal variations. The MicroBrute is able to achieve an remarkably wide tonal range with its one oscillator.
For the MicroBrute Arturia redesigned the sub-oscillator from the ground up. The new OVERTONE sub allows for the typical -1 octave square wave that thickens up the bottom end but goes beyond this with the Overtone control. The Overtone control allows you to bring in more complex harmonics that when turned all the way up result in the oscillator changing pitch to a 5th above the root.
This allows for some classic sounding leads and fatter basses. This control can even be modulated with the ENVELOPE or LFO via the mod matrix which creates some amazing new sounds never heard from a synth oscillator before.
The Ultrasaw builds two phase-shifted copies of the basic sawtooth signal. This effect, when turned up, gives you a slight thickening of the sound as it duplicates the sound of two saw oscillators close to the same pitch. You can then use the MOD MATRIX to route the LFO to the SAW which will add a third saw sound and allow to simulate a wider detuning effect.
The Metalizer takes the basic triangular waveform and ‘warps/folds’ it to create very complex jagged waveforms that are rich in high harmonics. This results in a hard sync sweep type of sound that is perfect for hardcore bass sounds or tearing leads. The ENVELOPE has a default routing to this parameter via the MOD MATRIX. Just turn up the ENVELOPE amount control, adjust your envelope to an interesting setting and you will hear the effect take hold.
The Arturia MicroBrute comes with a full featured LFO and a standard ADSR type Envelope. The routing of these modulation sources are configured in the MOD MATRIX. No other synth in this price range allows for this kind of flexibility.
The multiwaveform LFO has Square, Saw and Sine waveforms. It also has an output amount control allowing you to tailor the depth of LFO modulation. LFO range stretches from 0,1 Hz to 200 Hz allowing you to go anywhere from very slow longterm modulations to wild audio range effects.
A standard ADSR (Attack, Decay, Sustain, Release) envelope can be used for controlling the filter cutoff and the amplitude directly. You can then patch the output via the mod matrix and use the AMOUNT control to effect the pitch, Metalizer, pulse width or any other control destination in the MOD MATRIX.
The mod wheel allows for manual control of either the filter cutoff or the LFO amount. This allows you to play the modulation in real-time adding character and interest to your musical passage.
MicroBrute embeds the legendary Steiner-Parker multimode filter. This marvelous filter not only gives you a Lowpass mode like most other synths, but also Bandpass, and High-pass, making it a highly versatile and praised boutique filter.
The Arturia MicroBrute filter is based on the core of the legendary Steiner-Parker multimode filter and has been improved to deliver an even wider range of cutoff and resonance. Nyle Steiner himself has validated and approved these improvements.
The Brute Factor was inspired by a patch made on a famous vintage synth. Users would connect the headphone output to the external audio input resulting in a kind of feedback loop that is ideal for raspy and grungy sounds. This patch has been adapted and implemented internally in the MicroBrute.
With low Brute Factor settings, you will hear a gradual depth and roundness to the bottom end. When turned up above about 65 percent however, the MicroBrute can go berserk and produce barely controllable, crazy feedback sounds.
MicroBrute as an Audio Processor?
MicroBrute is more than a synth. It allows a return to audio experimentation by giving you the ability to process external sounds though it. The MicroBrute has an audio input with a pop-up trim pot for level controls on the rear panel. This will allow you to process any other sounds like voice, guitar or other synths through the MicroBrute’s filter, Brute Factor, and final output stages.
Arturia has added a new step sequencer for the MicroBrute. The step sequencer harkens back to some other step sequencer designs of the 80s but updates them in a way that goes beyond belief. The step sequencer allows for eight different sequences. These sequences can have up to 64 steps each and are stored in internal memory so that when you power down, they are retained.
You input the notes that you want one at a time and can insert rests using the TAP TEMPO button to create rhythmic patterns. Once you have your sequences, you can choose between many different ways to trigger and play your sequences.
When you change sequences while playing there are options to choose an immediate change to the new sequence or to have it play the current one to the end before changing. There are even more controls that are accessible via the free editor software that allow you to tailor the sequencer to your particular likes.
