Description
Choroboros by Kaizen DSP is a chorus plugin built around five prebuilt engines and 17 supplied sound cores. In version 1.0.5, the Free edition provides the Green and Purple engines without a time limit, signup, payment card, or licence key.
The two free engines use the same focused Rate, Depth, Offset, Width, Color, Mix, and HQ controls presented in the current release. Producers can use them for modulation, movement, width, and more experimental chorus treatment without activating a trial or purchasing the Full edition.
The one-time $49.99 Full licence unlocks Blue, Red, Black, all five prebuilt engines, engine import and export, and Create. Create is the commercial release's custom-engine workspace, combining the ten cores used by the prebuilt engines with seven additional supplied cores for 17 in total.
The current macOS release includes universal VST3, AU, AAX, and standalone formats, while Windows is available as a signed x64 VST3 installer with a manual ZIP alternative. Linux, Windows AAX, and a Windows standalone application are not currently released; the earlier GPLv3 public beta and its Dev Panel are historical and remain subject to their original terms.
