The DROP event allows whatever is currently playing over the top of the hour to finish, while removing any over-scheduled events from the previous hour.
There may be situations where you would want the next hour to pull forward into the current hour if the current hour is under scheduled. This is only useful if there are no Timed events in the next hour. This also runs the risk of hours running short and causing dead air.

CURRENT HOUR PUSH TO NEXT HOUR (^)
To manually override the Drop event at the top of the hour, the user can create a specialized clock that will carry over any excess scheduled items to the next hour.
To create the specialized clock, you need to only include a ^ character at the beginning of the Clock's name. The '^' character may be found by pressing Shift and then the number 6 on the keyboard.
PULL FORWARD (~)
To override the DROP at the beginning of the next hour, and allow the next hour to pull forward into the current hour, you can create a special clock. This also uses a symbol. If a clock starts with a '~' symbol and the play list is short, then the playlist will pull events from the next hour (one at a time) to play in the underscheduled hour until the top of the hour is reached.
Then it will move onto the next hour. It will not pull any form of Timed Event across the top of the hour because that event must remain in the hour it is scheduled to play in. If it reaches a timed event then the Play List will stop with an appropriate Break event inserted to hold place. This feature creates all of the complexities and is not recommended for normal operation.
PUSH AND PULL HOURS (&)
If a clock starts with a '&' symbol, then BOTH Play List features will operate (^ and ~). There will be no drop if there are extra events at the end of the hour, and the play list will pull events from the next hour if it is underscheduled.
Former Digilink-Xtreme users may be most comfortable with this type of setup. Again, we do not recommend this for normal operation as it is likely to cause problems. Problems can include under scheduled hours filled with dead air, or over scheduled hours that push you farther and farther off schedule. If you are to use this feature, you will have to pay close attention to the hour length and make sure it comes as close as possible to an hour length.
