Choose from 115 presets in different instrument and style banks to get you started.

Flux Pro is a multi-fx modulation plugin that transforms your sounds into colourful, characterful and dynamic tracks.

Do you want to add graceful stereo waves to your keys, dirty pulsing side-chains to your bass, complex striking filters to your synths or noisy mechanical glitches to your drums? Modulation is king and we're offering you the throne.

There are 3 customisable graphs which can perfectly sculpt your sound. Simply set the depth of the controls in the 4 effects slots, from which you can use a variety of 10 modulation effects. Are you in a hurry and need movement quickly? Easily drag 1 of the 48 built-in shapes onto the graph for fast and effective modulation.

"Flux Pro is easy to use with a decent choice of effects controlled by a powerful set of user-editable modulation curves. 10/10"

Attack Magazine

Music Tech - Choice Award & Value Award
