|                                            | Fixtures can be excluded from the grand master, for example, by setting **Master React** to None in the patch menu. For more information, see [Add Fixtures to the Show](/grandma3/2-4/patch_add_fixtures/) |

By default, turning the knob adjusts intensity. This can be changed in the Special Executor Configuration menu. To access the Special Executor Configuration menu:

1. Press Assign.
2. Press the Grand Master knob. The special executor configuration menu opens.

This menu can also be opened using the SpecialExecutor keyword in the command line. For more information about SpecialExecutor, see the [SpecialExecutor keyword](/grandma3/2-4/keyword_specialexecutor/) topic.

To read more about Executor Configuration, see the [Executor Configuration](/grandma3/2-4/executor_configurations/) topic.

The Grand Master is also displayed on the right side of the encoder bar on screen 1:

The Grand Master level can be set by the fader.

The Grand Master can also be assigned to any executor. See the [Assign object to an Executor](/grandma3/2-4/executor_assign/) topic.
