Flux Pro Render

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.

Modulation is King

Flux Pro has a range of effects from which you can use; Filter 1, Filter 2, Delay, Delay (Fixed), Width, Phaser, Chorus/Flanger, Rate Modulation, Ring Modulation and Utility.

Try shaping the Ring Modulation's frequency and harmonic amount to add mechanical flavours to your bass. Or maybe create some ethereal vocal delays by programming audio reverses an octave up with Fixed Delay's sample control. Then, apply a slow sine to the other Delay's time and feedback controls to create more movement.

Perhaps a mix approach, is your piano getting masked by a synth? Setup Flux Pro on the piano track with a boosted high shelf filter, some gentle chorus and additional width. Then, set Flux Pro's MIDI Input to the Synth, so that every time the synth plays the piano is given a little push to stand out in the mix.

Not good enough, want to get weird? Vary the formant filters' cutoff and resonance as if your music is flowing through someone's throat. Why not set the Fixed Delay to repeat every other bar at an octave lower so you can moodily duet with yourself on those lonely nights. Lastly, have quick oscillations of Rate Modulation to add percussive texture to your audio, and more importantly, save yourself the humiliation of recording a shaker track.

Choice Award & Value Award

"Flux Pro is highly effective at creating quite wild-sounding rise effects and glitched-out beats, but it can also be used for more subtle tasks. 9/10"
