Normally, you grab the surface of a fader and drag it vertically or horizontally, depending on its style. When using the fader itself as a slider, you may notice that values jump in larger increments, depending on the size of the fader and dragging speed. You can also change values in single steps by dragging the slider or knob while holding down the Control key.
Some of the fader styles have numerical displays. In these cases, double-click in the numerical field and enter a value. When you drag any of the sliders or knobs, the series of values that are sent out depends on the fader size and scrolling speed—not every consecutive value is sent out at smaller sizes. If you drag slowly in the numerical field, however, you’ll send consecutive values.
Knobs can be dragged either vertically or horizontally.
Buttons only send two values, the lowest and highest of their range set in the Object inspector. You change a button’s state by clicking it.
The default appearance of the text fader is like a value field that can be scrolled. Double-click to open a window and enter text for each menu position. Select the Behaves as Menu checkbox to use the text fader as a pop-up menu.
A vector fader allows you to scroll in two directions, and sends out two values: one corresponding to the vertical position, and the other to the horizontal position.
