New Firmware update available

Un Grain De Folie

Whether you’re looking for your first, affordable hardware synth or are a collector looking for original sounds and unique interface, MicroFreak is the synth you need.

This out-there little music machine features a versatile digital oscillator so you can create rare and interesting sounds with ease. Modes like Wavetable, KarplusStrong, Harmonic OSC, and Superwave give adventurous musicians the chance to explore totally new, unheard possibilities. Like having dozens of synths in just one instrument, both wild-eyed newcomers and seasoned professionals will fall in love with MicroFreak’s flexible, powerful synth engine.

Small but fierce

MicroFreak packs so much in to such a compact instrument, you'll wonder how we did it. We'd love to say it was magic, but it was pure skill and passion.

Physical modelling, wavetable synthesis, virtual analog, there is nothing as complete and exciting as the MicroFreak oscillator on the market. It's hard to believe from such a small synth, but here it is, ready for you to explore. Excite your creativity and reward your curiosity with a large, diverse sound palette. MicroFreak features 12 awesome oscillators, 5 bespoke Arturia engines, and 7 modes from Mutable Instruments.

There's a little freak inside you, and this instrument will bring it out.

The best of both worlds

Even though MicroFreak has a digital oscillator at its heart, “opposites attract” as the saying goes. That’s why we’ve included a lush-sounding analog filter.

Inspired by the trailblazing 12-dB SEM filter, you can make MicroFreak’s filter scream or whisper to taste. The filter is state-variable, and can even auto-oscillate! You can use this is any way you like, from taking the edge of the razor-sharp wavetable sounds, or automating the cutoff by modulating it with keyboard pressure or the in-built sequencer.

Wait. Did we mention that MicroFreak has a sequencer? And a mod matrix? Things are about to get seriously interesting...

Press Clipping

"With so many synthesis features packed into such a small box, it’s hard not to fall in love with Arturia’s latest hardware offering. (...) MicroFreak should be top of your ‘must-try’ list."
Electronic Musician
"It's a little package with a lot built in, I really enjoyed playing with it."
"Microfreak is a real magic box in terms of sound, especially if you feed the sound to good reverb or delay effects. The flexible oscillators in combination with the modulation matrix and the sequencer with parameter recording provide a sound rich in overtones with a lot of movement, the filter gives the analog touch. Especially the paraphonic sounds could convince us with results that would be difficult to realize with other synthesizers or plug-ins. The capacitive keyboard with polyphonic aftertouch is a creative input element, making the use of it very intuitively."
"This is just a synth that should be in every studio. (...) With the Microfreak you can enjoy yourself for a long time. What a genius thing!"
"This is an exceptionally brave new design from Arturia, which has the potential for lots of sonic brilliance. "
Music Tech
"Packing tons of power and innovative features into an affordable box, Arturia’s new offering is weird, wonderful and downright fun. (...) MicroFreak should be top of your ‘must try’ list."
"If you are looking to expand your tonal palette a little bit, it's definitely something well worth checking out."
"The Microfreak is certainly in the no-brainer category for all synth enthusiasts and electronic music producers, and not only because it packs a lot but most importantly because it brings interesting and refreshing elements to the table. The digital oscillator is fabulous, pressure keyboard and along with the modulation matrix it makes for an exciting synth with lots to offer. This is arguably Arturia’s best — real or virtual — synthesizer to date."
"This little synthesizer nails - in some ways cruelly - all currently existing multi-engine synthesizers to the wall. No other synthesizer currently on the market offers so many different synthesis engines in one instrument. In short: The MicroFreak is an absolute killer synthesizer, convincing on so many levels while allowing you to live out the pure fun of playing."
"The new MicroFreak synthesizer from Arturia is a very unusual instrument which is able to conquer the heart of any musician eager for experiments. It combines the virtually limitless possibilities of digital oscillators and tabular wave synthesis with the warm, charming character of analog filters."
"MicroFreak is an amazing little synth monster which can produce magic, weightiness, elegance, strength, and endless variation."
Strong Mocha
"A modern classic at the time of its presentation, Arturia MicroFreak is a very difficult contender to beat in its price range. If you take into account its sound versatility and its ability to create breakthrough sequences, and all for a price less than € 300, you have to rub your eyes to believe what you're seeing - and listening... Its variety of sound generators and the flexibility of modulation are incredible for a synth of this price. -Arturia wanted to raise very high what a low-priced instrument has to offer The Arturia MicroFreak digital synthesizer represents the intention of those of Grenoble to capture the imagination and the desire of the beginner users of synthesizers, but also of those more demanding and creatively advanced."
Future Music ES
"The modulation matrix is so powerful in itself, this is like a cherry on the cake but the cake itself is so incredibly well designed, actually, I would go that far and say it's the best synth arturia ever made."

Taste the spice, throw the dice

MicroFreak is packed with unique, exciting features that let you create music with a fresh perspective.

Record up to four automations, edit notes per step or use the innovative Spice and Dice sequencer functions to find happy accidents. Add randomization to create evolving, original patterns, and virtually rewire and reconfigure its signal chain and controls with the 5x7 modulation matrix.

This truly is a budget-friendly synth like no other.

The first thing that got me curious about the MicroFreak was its aesthetic. It looks great. When I finally got my hands on it, I knew immediately that it would be my go-to when I start a track or my inspiration when I was out of interesting ideas. Having no actual keys makes it even more creative because just sliding your fingers from note to note can create odd sounds and feels. I love that. It stays plugged in on my desk always ready to go.

I think it sounds great! It'll be a great, affordable little friend for on the go studio music production, portable performance rig etc. Good stuff.

With a very unique synthesis and a fast keyboard with many possibilities, this little hybrid has gone straight into my live set up.

“That’s a funny looking keyboard”

That’s right, it is. It isn’t really even a keyboard. It’s a PCB. Super-flat, with no moving parts. Will it track lightning-fast synth solos? You bet. Better than a traditional keyboard, actually.

Will it let you be expressive? Of course, it’s not only pressure sensitive, but also offers poly-aftertouch. This means each key can control parameters in a different way depending on how much you touch.

You can also use its USB, MIDI, and CV outputs to control instruments in your DAW and modular synths. This also means that you can also use MicroFreak as a controller to experience polyphonic aftertouch with cutting edge software instruments.

“There’s no way a budget synth can do all that!”

MicroFreak is here to break the rules
