Efx REFRACT

Arturia

Where to get itAvailable from Arturiaarturia.com

Efx REFRACT is a creative multi-effects processor that splits audio into up to 8 detuned stereo voices through its Refraction engine, then processes each voice individually with one of five effect types: Bandpass Filter, Comb Filter, Bitcrusher, Distortion, or Harmonizer. Designed for experimental sound design and creative processing rather than mastering, it can range from subtle modulation to extreme tonal transformation across synths, vocals, drums, and ambient sources.

Written from the manual and checked against it. How we check

Key Features

01Refraction processor generates up to 8 stereo voices with adjustable spread and dispersion
025 Mode Effect types: Bandpass Filter, Comb Filter, Bitcrusher, Distortion (4 algorithms), and Harmonizer
03Polyphonic effects processing with each voice treated individually
044 Distortion algorithms: Tape, Germanium, Soft Bounce, Sine Folder
05LFO modulation with wave selection and sync controls
06HP and LP filters plus dry/wet mix control
07Dual preset settings (A and B) within each preset

Things to Try

  • 01Increase Resonance on the Bandpass filter while adjusting Cutoff to hear a synth-like peak accentuation
  • 02Apply slow LFO to Comb Filter Cutoff with low Resonance for a subtle phaser-like effect
  • 03Use Bitcrusher Down Sample slider gradually from left to right to progressively reduce sample rate and create warmer, more retro tones
  • 04Explore the special relationship between Refraction Amount and the Mode Effect's primary control (Filter Cutoff, Bitcrusher Downsample, Distortion Drive, or Harmonizer Spray) for dramatic tonal variations
