FAC Chorus is a versatile chorus effect emulation designed to simulate the characteristics of the classic chorus modules with the flexibility of customising the parameters of the main components involved in the signal path.

The interface has a unique sober look and provides a great user experience. The knobs are very responsive, natural and follow a specific curve according to the parameters type.

The efffect is built upon two individual delay line paths controlled by common parameters. The behaviour of each delay signal path is defined by the chorus type parameter. Thick type means warm characters and emulates the behaviour of the BBD. Clean type, as the name says, provides a cleaner sound with a larger modulation.

FAC Chorus is suitable for any situation requiring chorus effects and can go from subtle to drastic changes, the factory presets provide an overview of the sonic panel you can obtain.

FAC Chorus doesn’t work in Studio One or Reaper

The advertising on the developer’s website says, "FAC Chorus offers features that may not yet be supported by available macOS hosts on the market. The audio unit v3 technology is not yet fully supported.” This language is ambiguous at best. There should be a clear warning that this AU plug-in will not work AT ALL in many DAWs. The demo videos for the chorus sound very good. But make sure you don’t buy this plug-in unless you are absolutely certain that your DAW supports AU v3. Also, the link to "FAC Chorus Support” simply takes you to the developer’s website which provides no method for contacting the developer. There is no email or support link. So it doesn’t seem likely that you’ll be able to get support if you have any issues with this plug-in or wish to report bugs after purchase.
