``Process'' is an over-loaded term, that is, a term having quite different meanings in different contexts (-E9).
Examples of macro-events are baking a cake, having a dinner party, flying from Rome to Paris.
It is worth remarking the distinction between macro-events and interval relations. Saying that a macro-event relates to the structure of an interval as whole means that if it consumes a certain interval it cannot possibly transpire during any subinterval thereof.
