Detailed Description

A button that runs one of the mode's functions when selected.

Appears on the param page as a row labeled .name and holds no value of its own. Selecting it runs .on_select in the mode's own context, so the function reads and changes the mode's state and sends MIDI just as process() does. A .confirm holding a short question guards a destructive command, putting a yes/no prompt carrying that question first. Left unset, the function runs the moment the button is selected.

void clear_clip() { /* ... *‍/ }
inline constexpr op::params::Action Clear {
    .name = "Clear Clip", .confirm = "Erase all clips?",
    .on_select = &clear_clip};
