How to Use

Add some audio files

The playlist is in the bottom-right corner, press the ‘+’ button

The button is pink at first to help you find it.

• Controls: Add tracks

Controls

Tap the screen to show/hide controls

Select animations from the top dropdown

• Controls: Shader dropdown

Sliders

Ajust sliders to change how the animation reacts to the music

Each animation will remember its settings.

• Controls: Sliders

Pay close attention to the top slider

The top slider adjusts stability (smoothness of animation) vs responsiveness (sensitivity to the music).

• Controls: Stability slider

Some sliders have an ‘auto’ icon

Tapping this icon (on the far right) disables the slider and matches that control automatically to the energy of the music. For example, if the slider affects the number of orbs on the screen, setting it to ‘auto’ means when the energy is high there will be more orbs, and when it’s low there will be fewer.

• Controls: 'Auto' slider

Memory Slots

The numbers [1] to [5] above the sliders are memory slots

Each animation has 5 memory slots to save your favourite settings. Tapping a slot activates it. When you adjust sliders, they will be saved into whichever slot is currently active.

• Controls: Memory slots

Memory slots can be copied

Long press a slot until it turns pink, then drag it over another slot. This duplicates all the settings from one slot into another.

• Controls: Copy memory slot
