142 Hog 4 Operations Manual
Assign a Parameter Offset
This setting allows you to offset the range of values over which a parameter varies. For
instance if one fixture is hung at an angle to the bar, so that it has a different pan centre-point
from all the others on that bar, then you could assign an offset so that the fixture appeared to
line up from a programming and operating point of view.
To assign a parameter offset:
1. Setu p → Patch → Edit Fixtur es
2. Select the Offset cell of the desired parameter.
3. Set, [ n e w v a l u e ] , En ter : Enter a value as a real world unit.
Important: Applying an offset to a parameter after you have programmed values for it into
your show will mean that those values will also be offset.
Naming Slots
Some fixture parameters are continuously variable, for example CMY colour mixing. On the
other hand some parameters, for example gobo or colour wheels, work in discrete increments
or ‘slots’.
The Fixture Library loaded into Hog 4 OS defines the fixture's default slots, displayed on the
Slot Toolbar, in palettes and the Programmer. When custom gobos or colours are used, you
can customize the show file to display a suitable name for each gobo or colour slot, chosen
from those in the fixture library.
To name a slot parameter:
1. Setu p → Patch → Edit Fixtur es
2. For the desired fixture, scroll right and select the Slo t cell for the parameter required.
3. Press Set, select the desired slot name from the list, and press Enter.
Releasable Parameters
Fixture parameters move to their default values when they are released. You can prevent
specific fixture parameters from returning to their default values, so that they hold their
current value until they are assigned to a new programmed value:
1. Setu p → Patch → Edit Fixtur es : open the Edit Fixtures window.
2. Click on the Re leasable cell for the required fixture parameter.
3. Press the Set key to assign the fixture parameter to be releasable or not as required.
