This is an AuV3 fx

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.

This is one of those apps where I pretty much try it on every track. It’s that good. Can’t say I leave it in place, but I’d say about 75% it stays.

This developer also had another app called Maxima that’s sort of an intelligent maximizer/exciter with a limiter function built in. I don’t understand the voodoo under the hood, but it consistently makes everything sound better. This one I add for every track, and then leave it about 90% of the time

Both of his current Chorus & Maxima apps take iOS sound to a more professional sounding level. Highly Recommended!

FAC is fast becoming one of iOS music production’s MVP’s

I had to come back and rate this superb chorus after FAC’s newest app Maxima came out to give this app its due. Sometimes when you discover a great app you jump right in using it and forget to go back and rate or write reviews. My delay rating the FAC Chorus falls into that category. This chorus is so good, so lush & organic, you can get lost in it’s ability to turn a normal synth pad into a velvet cloud of sound. Try this on Rhodes, acoustic guitar, background vox...seriously first class, professional chorusing that would make an Eventide unit blush. Highly recommended.

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.
