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.
