The secondend action is used with the firstend action to establish a repeated section of music with two different endings. Place the secondend action at the end of the first ending for the repeated music (which is usually true though not always also the beginning of the second ending) with a target that is the measure number for the repeated section of music. Leave the wait and times field blank with secondend events; these mechanisms are already built into the command. Leave the value field blank on secondend events.
