The auto style fader—the default style if you create a fader with a key command—changes
styles as you alter its shape and size.
The type of fader determines what events the fader sends out and responds to. In two
cases, however, the fader doesn’t send out events at all:
The cable switcher routes events to its different outputs. Clicking a cable switcher
object makes it step sequentially through the outputs.
The alias assigner changes the references (to an original, or parent object) of fader
aliases.
In general, a faders style is completely independent of its type. A cable switcher can
look like a button, a knob can send out MIDI or meta or SysEx events, and so on. The one
exception is the vector style fader—these behave in a special way, by sending out two (or
four, in special cases) messages at a time, depending on the mouse location within their
2-dimensional, vector window.
Use faders in the Logic Pro Environment
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.
