Push and Groove Turns Mutable Instruments Plaits Into a Free

I have been waiting for someone to do this properly. Mutable Instruments Plaits is one of the most influential macro-oscillators of the last decade, and the number of producers who want its engines in the DAW but have no Eurorack case is enormous. Push and Groove has stepped into that gap with MICRONIX, a free port of Plaits as a DAW synth. The move makes sense coming from Takahiro Oishi, the developer behind GROOVE60, whose whole thing is translating classic hardware behaviour into plugin form.

What Plaits actually is, and why a port matters

Plaits landed around 2018 as an open-source 12HP macro-oscillator. The design is almost modular heresy: sixteen synthesis engines crammed into one module, each one a complete voice. You get virtual analog, wavetable, FM, granular formant, string modelling, kick and snare synthesis, and more, all selectable from a single encoder with a couple of parameters and two CV inputs. The point was never deep editing. The point was range.

That philosophy transfers to a plugin badly if you try to make it a full synth. MICRONIX is best understood as a Plaits engine rack inside your DAW. Pick a model, shape it, print it. If you came up through Mutable’s line of thinking, nothing here needs a manual.

The engines you will actually reach for

Genre decides this more than the spec sheet does.

Kick synthesis. Plaits has a dedicated kick model, and for techno it is worth the install on its own. Tuning and decay land in exactly the range you want for a club kick, and it sits in a mix differently than a sample because you can push the pitch sweep harder without artefacts.
Granular formant oscillator. This is the sleeper for IDM and broken-beat work. It makes vowel-adjacent, breathing textures that nobody will place, which is half the battle in this scene.
String and modal engines. Plucked and struck models give you dub chords and percussive hits with natural decay that survive a heavy saturator downstream.
Noise and filtered models. Hats, textures, transitions. Not glamorous, but the noise engine is where a lot of your percussion layer will come from once you stop loading sample packs.

For electro and bass-driven stuff, the virtual analog and wavetable models are solid, but be honest with yourself. They do not replace Serum or your go-to bass synth for deep editing. They replace the “I need one more voice that sounds like hardware” moment.

The workflow reality

Because it runs as a regular plugin, the Plaits workflow changes completely. No menu diving through a tiny LED display. You get the parameters on screen, you automate them, and you bounce. The free aspect means you can put an instance on every percussion channel without thinking about CPU budget, which is not a luxury you get with paid synth bundles.

Push and Groove is also sitting on a nice body of free MIDI machine work with GROOVE60, the MIDI timing simulator built around a 96 PPQN grid. A Plaits port plus a groove tool in the same free folder is a genuinely useful starting stack for a track. Print a Plaits kick, feed other Plaits voices through GROOVE60’s timing model, and you have a hardware-flavoured skeleton before you touch a single sample.

Where MICRONIX falls short

It is a port, not a reimagining. The engine architecture is fixed, so if you want Plaits to do something the original does not, you are out of luck. There is no wavetable editor, no deep modulation matrix beyond what the original exposes, and no modulation of the kind Serum or Vital users expect. Some engines are also finicky about input levels. Plaits was built for Eurorack signal levels, and DAW gain staging does not automatically translate.

If you have the hardware module already, the plugin’s value drops considerably. The sound is the sound. You are mostly buying convenience.

Who should install it

Anyone who has been circling a Plaits module for years and never bought one. Anyone building a track on free tools and needing a synth that does not sound like every other free subtractive synth. Anyone who wants a kick and a hat engine that sound like a hardware voice quickly and cheaply.

The plugin sits comfortably alongside other free reference points in the current landscape, from Vital‘s wavetable work (as covered in our Serum vs Vital comparison) to the more experimental tools coming out of the free scene. It is not a full studio in one plugin. It is one very good module that happens to cost nothing.

Common questions producers have about MICRONIX

Does it require a Mutable Instruments account? No. Plaits is open-source hardware, and the port is distributed freely through Push and Groove.

Does it replace the hardware module? For sound design in the DAW, mostly yes. For live performance with CV modulation, no.

Is the CPU load manageable? Instances run light enough to stack several per track in typical tests, which lines up with the free-utility spirit of the release.

Can it save patches? As a plugin, yes. This is arguably the biggest practical advantage over the module.

The short version: if Plaits has been on your “someday” list, stop waiting. The port is here and it is free.
