The God Particle defaults to the settings used by Jaycen Joshua on every one of his mixes since 2021, but if you want to define and save your own presets, you can do so by clicking the disk icon in the top bar of the GUI and choosing a name for your preset.

User presets are then displayed in the preset drop-down menu under the user category.

If you want to return to Jaycen's settings, simply select the 'default' preset under the factory category.
