Arturia Efx REFRACT Plug-In, Download

Efx REFRACT is a stereo multi-effect with versatility at its core. Combining unison-based processing with a variety of secondary effects and modulation options. Effortlessly enrich, texturize and transform any sound, from experimental distortions to detuned harmonics.

Dramatic unison
Based on super unison architecture, Efx REFRACT delivers instantaneous size and character to your sound. Whether marking key moments or making sweeping transformations - bring any track to life with flare and multi-effect dispersion.

Effortless impact
Move from unfiltered stems to a wide and powerful sound with multiple voices. This can be particularly effective for building tension and emphasizing salient moments in a composition.

Spread your sound
Efx REFRACT's super unison architecture duplicates the signal up to 8 stereo voices. This can be used to spread and broaden any sound, and is the method behind the magic of this versatile multi-effect.

Geometric sound design
With an animated and responsive visual interface, weave various FX combinations together for a dispersion pathway that fits your wildest imaginations. Easily select the voices, filters, Mode FX, and LFO and watch the geometry evolve, along with your sound.

Expressive presets
Efx REFRACT comes with a host of presets to convey its multi-effect capabilities. Explore unique combinations of sonic dispersion and Mode FX, from Delay and Distortion to Texture and Transition.

Try it out
Try Efx REFRACT for yourself with this interactive widget. Cycle through the different effects and toggle the voice number and dry & wet control to go between an unfiltered sound to an enlarged and texturized unison sound.

Multi-effect magic
Efx REFRACT takes any audio source and spreads it across a dynamic and modifiable FX chain, allowing you to add energy, movement and power to your heart's content.

Refraction
The Refraction section of the plugin takes your input and can duplicate it up to 8 stereo voices. The Refraction 'Amount' then increasingly detunes and modulates each voice against one another to widen them. You can use this on its own to thicken and widen an input sound without additional FX.

Mode FX
The plugin comes with five additional Mode FX (BandPass Filter/Comb Filter/Bitcrusher/Distortion/Harmonizer) which are added onto each Refracted voice and processed individually, before being recombined at the output. This unique approach allows for novel, wild and creative results with only a few simple controls.

FX Dispersion
The Refraction 'Amount' disperses the chosen Mode Effect on each of the 'Voices'. Play around with the relationship between the Refraction Amount and Voices, and how setting them impacts the Mode FX controls.

Filters
Use the 'Input HP' to filter out some of the low frequencies from your input, which can help clean up the Distortion & Bitcrusher modes, and use the 'Output LP' to tame the Effect's high frequencies and remove some harshness to get smoother results.

LFO
Use the LFO 'Wave' to smooth things out or create choppy chaotic modulations. Experiment with the LFO rate to change the dynamics of the refraction amount.

The sound of unison
Unison refers to a process of multiplication, where the same sound or note is duplicated and played in parallel.

Like a string section in an orchestra, which has a wonderfully rich sound as a result of many instruments playing at once, unison replicates this for a chorus-like effect; with slight differences in phase leading to a sound that is more filled-out and enriched.

Efx REFRACT takes this approach of using multiple voices to enlarge and extend the width of a sound, which you can choose to do with or without the addition of powerful Mode FX.

FX modes
Choose to refract on its own, which can be used to enrich and widen a sound. Or disperse one of the powerful Mode FX, and unlock the uniquely expressive potential of Efx REFRACT.

Bandpass
Use the Bandpass filter for a classic attenuation effect, allowing you to create sweeping moods and muted atmospheres. Each dispersion voice will have a different Cutoff frequency centred around the 'Cutoff' control, creating a filtered widening effect.

Comb Filter
Use the Comb Filter for subtle and wild metallic-like reverb textures. With a high 'Resonance', play with the 'Cutoff' and Refraction 'Amount' values to change the size of your reverb, and use the 'Output LP' filter to tame the top-end.

Bitcrusher
Use the Bitcrusher for resolution deforming effects. Adjust the voice number to explore the tonal variations of a downsampled signal - with added voices progressively increasing tonality.

Distortion
For waveform warp, use the Distortion mode to add drive and gravel to your sound. Explore the refraction levels and notice how the sense of activity and chaos changes.

Harmonizer
For surreal shimmers and atonal showers, the Harmonizer adds unique pitch and spray to the dispersed voices. Go from alien detuning with just a few voices or a cacophony of sound with the voice number turned up.

Preset library
Need some quick-fire movement, variety, or texture? Efx REFRACT' preset library contains everything from mix enhancements to pure chaos in motion.
