Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge and are perceived as one.
The Chorus effect was originally designed to simulate several voices, just as if several persons were playing together the same notes, but with a variable delay between them. This is one of the typical effects that you can get with Blue Cat’s Chorus.
But this plug-in also enables you to drastically change the original sound and create deep pitch modulation or crazy ‘bubbling’ effects.
With the additional “Spread” control on the stereo version, the famous stereo widening and head spinning chorus effects are a few click away.

Main Features

  • Single voice vintage chorus effect.
  • Stereo spread control.
  • Sine or triangle LFO shapes.
  • In or out of phase mix control.

Kilohearts: Chorus

The Chorus enhances the stereo effect and presence of a sound by mixing it with delayed versions of itself. It’s like your own personal choir!

Delay knob: The average delay for the delayed voices.
Rate knob: The frequency of how fast to vary the delay.
Depth knob: How much to vary the delay.
Spread knob: Stereo width of the effect. A lower value will go towards a mono output.
Taps: The number of chorus voices.
Mix knob: The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.
Settings panel: Whenever you have your mouse cursor over a snapin there is a small arrow at the top right corner (not visible in screenshot). It opens a settings panel where you handle presets.
It also has a “randomize” button that can be useful.
