This is an AUv3 compatible effect which must be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels.

This shimmer effect is a combination of effects that creates an etherial wall of sound. The effect combines a digital delay and pitch shifter to create multiple harmonies before entering a rich long reverb with controllable filtering. The resulting effect is a monsterously huge sound adding a spacious atmospheric quality to any lead instrument or vocal.

The effect also features many beat synced modulation options with various modes of operation such as your basic pans and vibrato effects but including sweeps and morphing harmonies.

Finally to give the effect some real 'shimmer' we've added a harmonic exciter and a sustain section which samples and holds on to the sound to pull out and emphesise the harmonics.

The effect presents all the most frequently used controls to the user in a single screen, but each effect has it's own distinct set of controls and a total of 7 pre-configured touch pads allowing easy recording of controller data.

This plugin allows complete parameter automation and auto synced modulation to master tempo.

This is one of a suite of AUv3 compatible plugins which will also soon be available from 4Pockets.

Another great app

I have most of the 4Pockets apps. They are very useful. This one is crazy good. Highly recommended!

Fine reverb, but...

This effect works well with the touch instruments in GarageBand but I purchased it for use with my guitar and that’s where it comes up short. There’s seemingly no way to make it work the way I’d prefer and there doesn’t seem to be any sort of documentation/support. It’s unfortunate because playing around with the piano demonstrates a really flexible, interesting effect that I would really like to use.

In what way does it not work on your guitar? Even if its not suitable it does work. I find it rediclulous that just because this type of effect doesn't work as you wanted with your guitar that would justify a 1 star review? A shimmer reverb is designed for creating soundscapes, and not really a guitar effect, but nevertheless it does work well, especially with accoustic.

App is great, but...

Probably my favorite app right now, but it keeps glitching on Garageband IOS, and the effect keeps gets deleted from all the instruments after a error message pops up. Easy to get the effect back though by tapping power button off and on in the plug-in section where Shimmer is at.

Developer Response ,

There is an update on the way although it works fine for me in GarageBand someone else reported an issue which I'm looking in to.
