1-Chorus: One Knob Chorus

1-Chorus is a streamlined chorus effect designed to add width, movement, and character with zero complexity. Just one knob – Amount – controls everything under the hood: depth, rate, and mix are automatically adjusted to deliver a rich, musical chorus sound every time.

From subtle widening to swirling background, 1-Chorus adapts to your sound instantly, whether you're processing synths, guitars, vocals, or pads. No menus. No tweaking. Just instant vibe.

Dry Example:

1-Chorus, from 0% to 100% - from 100% to 0%:

Beta access on macOS. 1-Chorus is in open beta and not notarised by Apple yet — notarisation arrives with the stable release. Until then macOS keeps the quarantine flag it puts on every downloaded file, so there is one short step the first time you install.

Copy the plugin into your Components folder:
/Library/Audio/Plug-Ins/Components/

then run this once in Terminal to clear that flag:

sudo xattr -cr /Library/Audio/Plug-Ins/Components/1-Chorus.component

That is all: macOS then loads it like any other plugin, and Windows needs no setup at all. If your DAW still does not list it, write to hi.23dsp@gmail.com with your macOS version and DAW — beta reports get priority.
