In previous versions of Openlab the Automator Controls palette presented 5 slider bars to the user which could be assigned to any of the variables created within that automation. In Openlab 3 the user is able to create any number of controls within the palette and has a choice of a number of interfaces including slider bars, digital displays, clocks and progress bars.

After creating the variable that is to be controlled, open the Variable Controls palette, and click on the New button in the palette. A dialog appears, select the name of the variable from the "Control the variable:" pop-up. From the "Using a:" pop-up select the type of control you require. Click on OK. Each control then has an small edit button in the lower right corner from which the behaviour of the control can be set.

To remove controls from the variable controls palette drag them to the trash on the palette.
