Free Update

New WaveUser Engine

Upload your own custom wavetables - or any Wav or Aiff file ! - into MicroFreak via MIDI Control Center, then tweak your sound using Table, Position, and Bit Depth controls.

Sequencer Unison & Chord Voices

Now, every note that MicroFreak plays will reflect whether it’s in Unison or Chord mode, including sequences, played notes, and notes received externally.

Faster Oscillator Encoder Settings

You can now select a faster scrolling speed for MicroFreak’s Oscillator encoders in Global Settings; holding ‘Shift’ lets you toggle the original slower setting.

64 New Presets

Dozens of deep explorations of MicroFreak’s new WaveUser engine, culminating in an inspiring array of wavetable and bitcrushed timbres.

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. Stimulate your creativity and reward your curiosity with a large, diverse sound palette. MicroFreak features 16 awesome oscillator modes, including 5 bespoke Arturia engines, 7 modes from Mutable Instruments, and 3 oscillator modes designed with Noise Engineering.

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...

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.

MicroFreak allows me to get microscopic if I want to, but also provides a wide sonic palette without the need to obsess over every parameter. It’s just so much fun to interact with. You can’t go wrong!

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.

The keyboard is what really sets this synth apart from other synths at any other price point. You just tap on the keys and get this great, beautiful randomness that doesn’t sound disorganized.

“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
