If a preset has unsaved changes, the preset name will be written in Italic.

Tap over the “Save button” at the upper-right corner to overwrite all the changes immediately.

You can also use the contextual menu at the top-right and tap “Save as...” to save a rig as a new Preset:

“Save as...” is helpful if you have modified a Preset and want to save your changes as a new Preset, as tapping the save icon will overwrite the active Preset with your modifications.

In the save menu, you can name your Preset as well as assign it tags. Multiple tags have to be separated with a comma and a single space between them.

Tap "Change" to define the setlist where you would like to save the preset.
