"The firstend action, which is used in tandem with a corresponding secondend action, allows you to create repeated sections of music with different endings (Ending #1 and Ending #2). Get ready for a bit of a brain twister here: The firstend action is placed at the beginning of the first ending and its target is the beginning of the second ending. It's equivalent to a relocate metaevent with a target that is the second ending start measure number and a wait value of 1 (it performs the action on the second pass). In this way, the firstend action defines the front boundary of the first ending. Leave the wait and times field blank with firstend events; these mechanisms are already built into the command. Leave the value field blank on firstend events."
