Refractalizer

Make it grain

Refractalizer is a new kind of synthesizer that makes granular synthesis more musical. It lets you bend time, transform samples, and morph effortlessly between rhythmic chopping, granular sound-scapes, and conventional synthesizer sounds. It’s a playground for sonic explorers: a temporal modulation workstation where drum loops become chords, voices become synth leads, and simple ideas morph into entirely new musical worlds.

Introducing Refractalizer FX

COMING SOON IN V1.1

The Refractalizer 1.1 update expands our flagship VSTi into the realm of real-time processing. You now get the best of both worlds: a dedicated Refractalizer FX plugin for direct track processing and an updated VST instrument capable of capturing audio via sidechain.


Capture and refractalize audio in real-time with the new live rolling buffer. Layer multiple buffers of different lengths to create evolving variations, then use Commit to save any moment as a sample or Freeze to lock your loops in place. With dedicated Mix and Feedback controls, Refractalizer FX performs like a granular delay or looper, all while remaining fully playable via external MIDI.

Free for current owners. If you already own Refractalizer, this update is yours at no extra cost.

Don’t own it yet? Purchase Refractalizer now at our current discounted price to lock in your access. You’ll get the 1.1 update for free upon release before the price increases to $149

The Ultimate
Time Warper

Discover hidden depths of your sounds between the milliseconds with Refractalizer’s core magic: the ability to slide seamlessly between rhythms, tones, and textures.. Refractalizer’s custom granular engine can accommodate any scale of time-stretching no matter how extreme, with subatomic resolution that captures every microsonic detail with sample-accurate precision. Unlike typical granulators that rely on randomness, Refractalizer’s grain rate can be controlled by MIDI notes allowing you to play the grains as a synth.

One Sample, Infinite Variations

Throw in a single sound and bend time to reveal hidden harmonics, micro-textures, and unexpected musical moments. By slowing down the buffer playback while grains overlap, you can transform tiny slices of audio into pads, drones, shimmering atmospheres, or rhythmic phrases. It’s the ultimate elaboration machine, perfect for exploring and manipulating existing musical ideas without layering more and more parts.

Multiple Samples, Infinite Dimensions

The multi-buffer system lets you load an unlimited number of samples and fade smoothly between them. Morph between drum hits, switch between variations of a loop, or blend bass layers into one evolving super-sound, all with true interpolation and no abrupt switching. It also works tonally: stack synth voices, vocal snippets, or orchestral hits and move between them like an infinite wavetable made from your own sample library.

Multi-modal Morphing

Refractalizer lets you slide between tempo-synced rhythmic divisions and audio-rate modulation. Go from 16th-note chops to pitched tones to exponential bouncing ball FX with a gesture. Then widen the sound using our unique stereo grain cycling – grains bounce between left and right channels, creating rich phantom-center images and stereo harmonics you can’t get from chorus, EQ, or widening plugins.

Under the hood

BPM <> Hertz

Interpolation

Most devices force you to choose between rhythmic subdivisions or arbitrary millisecond timing. Refractalizer unifies them, allowing interpolation between BPM-locked divisions and precise Hz values. Sweep seamlessly from 1/16 notes into a melody, or create endlessly evolving textures that drift in and out of time.

Polyphonic

Grain-Rate Synthesis

Granular synthesis is most often used as a texture generator. Refractalizer turns it into a polyphonic instrument. Grain rate can be controlled directly by MIDI notes, allowing grains themselves to become the oscillator. You can play leads, basses, chords, and percussive parts with the precision of a synth but with all the character of micro-sampled audio.

Multi-Buffer

Interpolation Engine

Load multiple samples and interpolate smoothly between them manually or automated with an LFO. A cross between Granular and Wavetable synthesis, the multi-buffer interpolation engine opens up wild new possibilities for sound design.

Stereo

Grain Cycling

Instead of spreading the signal with modulation, Refractalizer distributes successive grains across L and R channels in selectable patterns. At slower rates this adds movement and a natural pulse; at high grain rates the ear can’t localise the switching which creates phantom harmonics and a psychoacoustic widening effect.

“DataMind Audio has been on such a tear of late inventing entire new categories of sound. Refractalizer’s innovation within granular synthesis is astounding.”
— Daedelus

Frequently
asked questions

What is Refractalizer?
Refractalizer is a new kind of synthesizer that builds on granular synthesis concepts and makes them more musical and controllable. Unlike typical granular synths Refractalizer allows for extreme time stretching and seamless fading between BPM-synced and frequency based modulation. It also has multiple buffers which means you can drag more than one audio sample, as many as your computer can handle in fact, and seamlessly interpolate between them. These, combined with many other innovative features, enable Refractlizer to create a much wider palette of sounds than other granular synths.
What is a multi-buffer system?
Refractalizer features a powerful multi-buffer system that allows you to load as many samples as you like into its buffer. Similar to working with a wavetable, you can interpolate between these samples by either manually controlling or modulating the Sample Selector slider. This opens up an entirely new palette of creative possibilities for sound design and music production. Unlike traditional wavetables, you’re not limited to single-cycle waveforms. Refractalizer lets you interpolate between samples of any length or character, enabling expressive transitions and unique textures that go far beyond conventional synthesis workflows.
Can I put my own sounds in Refractalizer?
Yes. Any number of samples can be loaded into the buffer or drag and dropped directly from your sample folder.
How is Refractalizer different from other granular and samplers?
What sets Refractalizer apart from traditional granular synths and samplers is that it fuses three advanced sound-shaping concepts into a single, fluid instrument. Its multi-sample buffer lets you load and smoothly interpolate between a whole library of samples, allowing seamless morphs between drum hits, loop variations, or layered tonal material without any of the abrupt switching found in traditional samplers. Its custom granular engine delivers extreme time-warping with sample-accurate precision, and even allows you to “play” grains melodically via MIDI. Finally, its multi-modal morphing system lets you glide effortlessly from tempo-synced rhythmic patterns to audio-rate modulation.
What does it mean to morph between tonal and rhythmic time domains?
Rhythmic or tempo-synced time refers to grain rates that follow your DAW’s tempo, expressed as musical subdivisions like 16th notes, triplets, dotted divisions, and so on. In contrast, tonal, audio-rate, or free-running time is measured in Hertz and runs independently of the host tempo. Refractalizer lets you morph smoothly between these two domains. For example, you can start with grains triggering in perfect sync with your track, much like an arpeggiator, then gradually transition into free-running audio-rate speeds. As the rate increases, the rhythmic pulses blur into pitch, turning your grain sequence from a tight rhythmic pattern into a playable synth-like tone.
