Flux Mini

What it does

A free AUv3 that modulates a track from a shape drawn on a graph. The shape drives amplitude, a low pass filter or a high pass filter, picked by three buttons along the top, and a resonance control sharpens the filtering. Points go in on a double tap and come out the same way, and a sync control sets the division the shape repeats at, down to eighths. Mix, snap to grid and a visualizer toggle sit alongside, and twenty presets ship with it.

In the demo

Jade runs it in AUM on two finished mixes sent in by viewers, stepping through presets to a riser and to one called fake chain that builds a sidechain inside the app. She then draws shapes by hand, holds a sung note through it so the filter movement is audible on its own, and puts it on a DrumComputer pattern.

Worth knowing

At full mix it swamps a whole track, so Jade keeps it pulled back or on single parts. She was unsure on camera whether it runs on iPhone.
