There are two types of Macros in ZerOS - Fixture Macros and User Macros. User Macros are not available on FLX S consoles.
The term macro, is simply used to mean a shortcut for the console doing a task for you.
On FLX, the Macro window is displayed on the internal touchscreen, by pressing the Macro key, to the left of the internal touchscreen.
On FLX S consoles, the Macros tab will be available if you select a fixture which has fixture macros available. The Macros tab will always be the very last tab to be displayed along the top of the touchscreen, so you will often need to scroll the attribute tabs to the end to access it.
Some fixture functions, such as resetting a fixture or switching a fixture's lamp on, are accessed via Macros rather than using a particular parameter within one of the attributes. This is to make controlling the fixture's function easier. Often, fixture functions require parameters to be at certain levels, for a certain amount of time, for the function to be activated. Fixture macros have all of this information stored in them. It also means you don't need to trawl through attributes and parameters to find the function you are after - you can just go to the Macros window, and see the available functions for your patched fixtures.
To create macros for your currently patched fixtures, go to the macros window, and press Automatically Create Macros.
Macros will be created in alphabetical order, to help you find the function you are after. The total number of fixture macros available on all FLX range consoles is 240. You will see fixture macros specific to the fixtures you have patched.
To apply a macro, select the fixture, and then tap the fixture macro you need.
You may find that some parameter details of your fixtures, are simply labelled "Macros". For example there are multiple details of the "Control" parameter in this image simply named "Macros".
This means that macros can be used to control that parameter, rather than using the parameter manually.
If your fixture has a "Lamp On" macro, and you use this to lamp on multiple fixtures, ZerOS will automatically strike your lamps one by one in the order of selection. This avoids striking all lamps at the same time, which could lead to overcurrent.
