Fader Operation
Normally, you’ll grab the surface of a fader, and drag it vertically or horizontally,
depending on its style. When using the fader itself as a slider, values may jump in larger
increments, depending on the size of the fader and dragging speed. You can also
change values in single steps by dragging on the slider or knob while holding down
Control.
Some of the fader styles have numerical displays. When there is a numerical display,
you can double-click it, and type in the desired values. When you drag on 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 on the numerical field, however, you will 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
Parameter box. You change a button’s state by clicking on it.
The default appearance of the text fader is like a value field that can be scrolled.
Double-click to open a window that allows you to enter text for each menu position.
Enable 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.
