Glossary 1027
window type Status of the window as a float window or a normal window. Float
windows always float in the foreground and can not be hidden by normal windows.
Also see float window.
Word Clock Clock signal required by digital audio interfaces to ensure the sampling
rates of connected devices run synchronously. When two devices are connected via a
standard digital audio interface (such as S/P-DIF or ADAT optical), Word Clock is
transmitted via the audio circuit. If you want more than two digital audio devices to
communicate with each other, you will need to use separate Word Clock ports for
synchronization, in most cases.
word length See bit depth.
XG Extended General MIDI standard from Yamaha, compatible with Roland GS.
zero crossing A point in an audio file where the waveform crosses the zero amplitude
axis. If you cut an audio file at a zero crossing there will be no click at the cut point.
zoom An action that enlarges (zooms in on) or shrinks (zooms out from) the display in
a Logic Express window. The Zoom tool, and the zoom controls found in the lower left
and upper right corners of windows, are both used for zooming tasks. Also see zoom
control and zoom level.
zoom control The control that appears at the bottom right of some windows, such as
the Arrange. The zoom control slider allows you to navigate through the entire length
of the currently displayed project. The lines on the left and right of the slider can be
clicked to zoom in and out by a fixed percentage.
zoom level The amount that window contents (tracks and regions, for example) are
magnified. Zooming in to a high level allows you to make more precise edits.
Conversely, you can zoom all the way out to see the entire project and work on very
large sections.
Zoom tool This tool allows you to zoom in on any part of the active Logic Express
window. You can choose this tool from the Toolbox, or activate it when using other
tools by holding down the Control key and clicking.
