Display Levels in the Editors
Normally, the editors are at the lowest display level, which shows individual events.
Clicking the UDL button, at the upper left corner of the editor window, allows you to
move up one level in the hierarchy. As an example, if you are currently looking at the
events in a MIDI Region inside a folder, the display will switch to a view of the MIDI
Region in the parent folder.
In the Matrix and Hyper Editors, this step up the display hierarchy means that you will
then see an Arrange window. In this scenario, a change to the lowest display hierarchy
level will cause the relevant editor to reappear. At the Arrange level, you will see the
local menus of the Matrix or Score Editors, which also contain all of the Arrange
window functions. Double-clicking on a MIDI Region opens the Hyper, Matrix, Score
Editor, or Event List display of the contents of the MIDI Region. Use of this facility, in
conjunction with the UDL button allows you to quickly switch to another MIDI Region,
and edit its contents.
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.
