To update a group, it usually makes sense to recall that group first. To do this, tap the group, or if you wsih to adjust intensities, double tap the group. Then make a new selection of fixtures, or tweak the intensities, and then press Update followed by touching the specific group on screen. This updates whichever group you touch on the touch screen. Updating a group will update the contents of that group but will not alter the name of the group.
On FLX, Groups can also be updated using syntax. Make a new selection of fixtures and then type one of the following commands:
Update Group 1 4 Enter
Update, Group 14, Enter,
This updates Group 14
Update Group touch group
This updates whichever group you touch on the touch screen. You do not need to press the “group” button if the groups window is already displayed.
