to “revert to default ” is only for one parameter to reset. How about if I want to reset its settings for the whole sop?(all the parameters in that sop) (can I do it in one go? instead of doing it one parameter each time)
What Simon meant was the Presets button which is in the stowed bar at the top of the parameters. Unstow the bar, click on the Presets button & select “revert to and restore permanent defaults”.
