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.

Spews audio out the main speaker

Audio comes out the main speaker rather than the ear speaker causing a feedback loop

Juno style chorus

While the developer doesn’t specifically state what chorus this app emulates, this is THE chorus app you absolutely need to get if you’re looking for a chorus that sounds similar to that of the Junos. You’ll get lost in the rich, swirling sea of the Juno chorus sound. It truly sounds amazing, plus it offers plenty of flexibility to tailor the sound to your specific taste.

My only complaint is that it only supports AU connectivity. No Audiobus or IAA as far as I can tell with the apps I use. So this limits you to using it inside apps that support AUs.

A chorus effect is not something I really needed for my iOS music pursuits, or at least that’s what I thought. Adding some subtle depth to a soft synth can create new characters of sound. But FAC Chorus is easy to use and can also be super sweet and creamy and put some thickness to your sounds. I love it! Essential!
