Chorus/Flange

Experience the depth and richness of the chorus effect—add harmonic structure to your sound as if multiple layers are playing in unison.

The Chorus effect adds a rich, shimmering quality to sounds, creating the impression of multiple sources playing in unison. By slightly delaying the input signal (around 15ms) and detuning it through modulation rate and depth controls, the chorus effect can range from a subtle ensemble sound to a more pronounced, warbling texture.

Chorus is ideal for thickening pads, strings, vocals, and guitars, enhancing the overall audio texture.

How Chorus Works:

  • Delay: Adds depth by delaying the original signal and mixing it back.
  • Modulation Rate & Depth: Controls the intensity of pitch shifting, from subtle to dramatic.

Flanging vs. Chorus

Flanging combines two identical signals, delaying one by a small, modulating amount to create sweeping “comb filter” effects. Often fed back into the input, flanging produces an intensified resonance effect, making it ideal for bright strings, drums, and cymbals.

Key Controls Overview:

  • Delay: Sets delay time. Flanger effects use shorter delays, chorus effects use medium to long.
  • Feedback: Controls how much effect signal is fed back to the input, intensifying the resonance.
  • LFO Rate: Determines the oscillation speed of the sound.
  • LFO Sync: Synchronizes the effect to your track’s tempo.
  • LFO Freq. Mod: Adjusts modulation depth for dynamic sound shaping.
