Chapter 1 Using Logic 23
Clicking the UDL button in the Event List moves you up one level in the hierarchy, just
like the other editors. In the Event List, however, the form of the display remains the
same but instead of a listing of individual events, you’ll see a list of Regions—along
with their position, name, track number, and length. The MIDI Region that you were
just editing will be selected in the list of Regions.
Once again, double-clicking on a MIDI Region (or using the Go Into Folder or Region key
command) takes you back to the lowest display level, showing the contents of the MIDI
Region.
Double-clicking on an Audio Region opens the Region in the Sample Editor.
In the Score Editor, clicking on the UDL button, or double-clicking on the background
takes you to the higher display level. Unlike the other editors, individual events can also
be edited while in higher display levels in the Score Editor. Double-clicking on a staff (at
an empty point), takes you back to a lower display level.
Selecting the Working Area
The scroll bars are situated at the right and bottom edges of a window, if you can only
see a portion of the total working area in either the vertical or horizontal dimension.
You can move the visible section by clicking the arrows, or grabbing and dragging the
scroll slider. There are two points of note:
• The size relationship of the scroll slider to the entire scroll bar corresponds to the size
of the visible section of the window, in relation to the overall window size.
• The visible section changes as you move the scroll slider.
The X/Y scroll element is situated at the bottom left corner of the window. By grabbing
and dragging it, you can move the horizontal and vertical window section, as if you
were dragging both scroll bars simultaneously. When the cursor hovers over the X/Y
scroll element, a crosshair icon with four arrowheads is displayed.
You can also engage the X/Y scroll feature by holding down a third button (the mouse
wheel button, for example), and moving the mouse. The distance of the mouse pointer
position from the initial clicked position determines the scrolling speed.
Note: Touching the background of the Arrange Window while holding Shift-Control
also allows you to scroll the window both horizontally and vertically.
