FAQ
What does the chorus do?
It layers slightly detuned copies to make one voice sound fuller and wider.
Will it blur speech?
Keep it moderate on voices so words stay crisp; thin leads and vocals gain the most body, and you can layer Shimmer for extra width.
How is it different from Shimmer?
Chorus Fat thickens and widens the sound with detuned copies, while Shimmer adds bright treble and a glassy sparkle on top.

What the fat chorus effect does
It stacks several slightly detuned, delayed copies of the sound, so a single voice becomes thick, wide and lush. The result feels bigger without changing the words.
Gentle width or full ensemble
A soft setting adds a tasteful spread and richness. A stronger one builds a shimmering, ensemble-like wall of sound.
Tips
- Thin voices and leads gain the most body from a chorus.
- Keep it moderate on speech so words stay crisp.
- Layer with Shimmer for an even wider, glassier tone.
