Caelum Audio Flux Mini 2 v1.0.2 AU AUv3 VST3 AAX WiN macOS [FREE]

Caelum Audio Flux Mini 2 is a free modulation effect for producers who want rhythmic movement, pulsing volume changes and animated filtering without drawing automation for every adjustment. Its editable graph defines a modulation pattern that can drive filter cutoff, resonance, amplitude and wet/dry mix, with individual depth sliders controlling how strongly each parameter responds.

Use it for sidechain-style pumping, repeating filter sweeps or more intricate rhythmic textures. Low-pass, high-pass and band-pass filter modes offer different ways to shape the tone, while simultaneous modulation lets one pattern affect several controls at once. Timing can follow your DAW tempo or use milliseconds, and MIDI triggering provides another way to start the movement.

The graph supports curves shaped with two control points, and 20 included presets provide starting points for your own patterns. You can also send the graph as MIDI CC data to control compatible destinations. For hobby producers working in Windows hosts such as FL Studio or Ableton Live, Flux Mini 2 offers a focused way to add motion to static sounds.
