Flux Mini is an AUv3 audio effect that adds life, character and dynamism to your tracks. The customisable graph creates a shape which affects either the amplitude, low-pass filter or high-pass filter. You can emphasize the frequency modulation with the resonance knob too! New: route MIDI to the plugin to trigger the envelope. MIDI note-ons can either retrigger the envelope or trigger envelope one-shots. From simple side-chains to manic modulations, sculpt some life into your sounds - flux it up and have some fluxing fun! Pre-loaded with 20 presets to get you going, it won’t be long before you’ve built a plethora of shapes to accentuate your fantastic music. As it is an AUv3 plugin, it works within iOS and iPadOS hosts such as Garageband.
