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 sounds FAT

Have not been doing much music recently (that’s about to change). However had to get this Chorus app, Lovely Stuff.

The graphics are, silky smooth and a joy to use. 👨🏽‍💻
The sound is also silky smooth and a joy to hear. 👂🏽

Just what you would expect from a chorus effect, top stuff.

The developer is also very pleasant and listening.

A while back I read a few comments (forums) that mentioned high cpu usage, - don’t know what devices they were using 🙄 but my mini2 makes those comments seem untrue (for me at least).

What the doctor ordered

Needed a good chorus to smooth out the rough edges of Oriental Strings and this does it with perfume and spice. The holy grail of iOS chorus plugins. In the wrong hands it becomes an extra synth. Absolute bargain!!

And I know that I’m not using it to its full potential; it’s still lovely.
