Arturia Efx REFRACT is a unique stereo multi-effect that combines unison processing with a bunch of secondary effects to mangle your audio in all sorts of creative ways. And here’s the best bit: Arturia Efx REFRACT is FREE for a limited time! Don’t miss this awesome Christmas gift from Arturia!


Arturia Efx REFRACT

Arturia’s annual holiday gift has become a beloved tradition. In recent years, the French developer generously stuffed our stockings with limited-time freebies like MS-20 FilterTape MELLO-FIChorus JUN-6, and Rev PLATE-140. This year, they’ve come up with something extra-special. Arturia Efx REFRACT is a multi-effect unlike any other, and it’s available for FREE for a limited time!

Efx REFRACT revolves around the concept of unison processing. The plugin duplicates your input signal up to eight times, creating a stack of voices. You can then turn up the Refraction amount to introduce slight pitch variations and modulations, thereby thickening and widening the sound. Think orchestra vs. string quartet.

5 Secondary Effects

But that’s just the beginning. Arturia Efx REFRACT also includes a second processing stage that offers a choice of effects, including bandpass and comb filters, a bit crusherdistortion, and a harmonizer. The cool thing is that these are applied to each “refracted” voice individually and differently. The higher the refraction amount, the larger the differences between the effects on each individual voice. There’s also an LFO for modulating the refraction amount and secondary effect.


This unique idea should lend itself to all sorts of creative experiments and unique sounds. According to Arturia, Efx REFRACT can deliver anything from subtle size and character to sweeping transitions and transformations. Fascinating stuff!

Price and compatibility

Arturia Efx REFRACT is now available FOR FREE on Arturia’s website until January 4, 2024. In recent years, Arturia’s servers sometimes struggled to handle the amount of requests, to have a little patience if you don’t get through right away.

After January 4, Efx REFRACT will presumably become part of Arturia’s regular line-up of effect plugins. It should also become part of the next version of the Arturia FX Collection.
