CHAPTER 3: Key Audio Design Features About Events Events offer a way to take actions in a HAL System using a time of day clock. The Event Manager interface is intended for Halogen programmers (not end users) to create and configure all events. Events allow actions such as an automatic preset recall at 8 am every Sunday for a traditional church service, and then a second event recalls the 10 am contemporary service preset. Or turn up the background music and turn on the neon sign for happy hour from 4 pm to 6 pm weekdays. If school lunch is in the cafeteria weekdays from 11:45 to 1 pm, but at all other times the room is for band & choir classes, a toggle event that sets up the HAL system for lunch at the proper time, but otherwise provides the band class settings could be another event. If the lunchroom is used in more than just two ways, maybe as a homeroom from 8 am to 8:20, and detention from 3:30 to 4, you'd set up several consecutive command events that follow each other: homeroom, band, lunch, band, detention, Thursday evening choir practice and Saturday yoga class. NOTE: Note: If you need actions that never relate to a clock, date, or a timer, such as simply pushing a button somewhere to change settings, you don't need events at all - you can link directly to the button action - see "About Control Links" on page 106. What is an event and why would I use one? An event is a way in Halogen and HAL to activate an action using a date and time, a time interval, or a button press followed by a timeout to undo the button action. After activation, an optional inactivation of the action can be set using time. Some examples of action activation or deactivation are toggling one or a group of parameters (e.g., mutes, audio matrix cross points). Or an action can activate a preset (a set of parameters to apply then later remove). When should I use events? Use an event when you want do something on a specific or recurring date and/or time. How do I create events? The Event Manager in Halogen software is used to create, configure and test events. What does the Event Manager do? The Event Manager in Halogen is the dialog in which all events are created, configured, edited and optionally linked to other controls such as toggles, commands, or selectors. How do I give the end users control over an event? In addition to using the clock to drive the activation and/or deactivation of events, you can also link to an event's Active Trigger and/or Inactive Trigger buttons. NOTE: Note: giving end users control of an event, means that BOTH a clock/time AND an end user button on a Digital Remote or web page or 3rd-party touch screen are driving the activation and/or deactivation. If you need actions that are only triggered by direct end user button presses, and do not need a time of day at all, you do not need an event. You need a control link.
