I've only used Hog so I'm not 100% what the home/locate function would be, but...
If 'locate' means 'show me where it is' then that's Highlight. Select fixture(s) and hit Highlight, and fixtures will go to 100% intensity, white, and remove beam parameters such as gobo etc. Pressing highlight again restores them to previous state.
If 'home' is 'go to 50/50 pan/tilt' then either program a home palette for all fixtures and use that, or holding the decimal point and touching encoder(s) or a kind key (eg position) will send that function to its default values.
Home would normally place the fixture at 100%, set Pan & Tilt at 50%, clear any gobo, reset zoom and focus etc to 50%. A very good feature when first using the fixture, or clearing any values that have tracked though.
There is no direct home button. But when you let the console create the auto-palettes you find something similiar in the Position directory: Open White. Thats a global palette that includes all parameters and sets all values to default. And also brings those parameters into the programmer. Highlight will only do this as long as highlight is enabeled. Good for finding fixtures and focusing. You can also create your own high/lowlight palette.
Or if you don't use auto-palettes, select all fixtures when the desk is idle and not playing back any programming, put them to 100% and Touch all parameters then record to a palette using the mask to 'force' all IFCB parameters into one palette type.
You can also create highlight and lowlight palettes that can automate the process for you.
For example make a low lite palette that sets all fixtures to blue, irus/zoom 50, gobo open, at full.
Make a highlight palette that sets all fixture to ow @full open gobo zoom/irus 30
Now when you dial in 701 with highlight on, all the other fixtures will go blue, open beam, @full and 701 will be white open and the beam slightly narrow.
Hitting next will set 701 into the lowlight state and force 702 to be open white @full and slightly narrow. This is a good way to find fixtures when you have a lot of them.
Not directly but you can do it per Kind by holding down the "." and press the Int, position, colour and beam button. This will put all the values to your defaults.
It will be nice if we can do "." Fixture for defaulting all the parameters...............
