An action performed when new composite members first touch existing members.

Notes may have an $OnJoin action. When a note that was not previously a member of a composite is dragged to touch a note with an $OnJoin action, the $OnJoin action is performed on the dragged note. If a note touches more than one note in the composite, each $OnJoin action is performed in turn.

In the context of an $OnJoin action, designator 'this' references the note joining the composite whilst 'that' references the note within composite to which it is now adjacent.
