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.

User Comments & Reviews

The generous offering of a full range of time based modulators consists of very basic but powerful and versatile effects. The Blue Cat Chorus for example, is ALWAYS the first one I try for super rich detuning and haywire coloured effects, but at the same time, I find it can throw just the right wisp of mist into a warm string pad. - Max Debutante

"Looking very much as if it were inspired by Eventide Clockworks' 1970s effects, this terrific freebie comes in a wide variety of plug-in formats and provides a terrific-sounding chorus with a reserved but flexible smattering of controls. A random mode generates presets if you're not inclined to set them up yourself, and both mono and stereo versions are included." - Computer Music Specials [excerpt on musicradar.com]
