Worlds and filters can be used as tools for programming, playback, or filtering information in some windows.Worlds are used to limit access to fixtures and attributes.Filters are used to prevent attributes and layers to pass a filter. Typically in store, update, and recall actions but also to filter what is displayed in some windows.The selected world and filter always dictates what is possible using the programmer.Worlds and filters can be assigned to some objects. For instance, a sequence or a preset. The world or filter then dictates what can be played back from or stored into the object.WorldsWorlds contain information about fixtures and attributes.Worlds are used to prevent access. Fixtures and attributes not in the active world are removed in some windows and cannot be used in programmer actions.They are stored in the Worlds pool. This can be created like any window using the Add Window pop-up.World pool with world 1 selectedThere is always a selected world. The selected world has a yellow frame around it.There is a default world from the factory. It is always world number 1 and it is called "Full". This automatically contains all fixtures and all attributes. This world is locked and cannot be edited.FiltersFilters contain information about attributes, layers, and patch information about the fixture (Name, ID Type, Fixture Type, Layer, and Class).Filters are used to block values from being stored or recalled. For instance, assigning a filter that blocks dimmer values as a playback filter on a sequence, prevents the dimmer values from being played back from that sequence. Assigning a filter that blocks certain ID Types to a Layout will hide these fixtures in the layout view.Filters are stored in the Filters pool. This can be created like any windows using the Add Window pop-up.Filter pool with filter 5 selectedThere is always a selected filter. The selected filter has a yellow frame around it.A new show will have some default filters from the factory. The first one is called "Open". It contains all attributes and layers. If the attributes structure changes, then this filter is automatically updated. The filter is locked and cannot be edited.The other filters are named after the location they are automatically assigned. For instance, the Sequence Sheet filter (number four) is assigned to the sequence sheet in the predefined view. These filters are not locked and can be changed.If a different filter than number 1 is the selected filter, then the At key flashes to indicate that there is an active filter.
