Apple Logic Express 9 - Manual (Page 1268)

Content Link mode The chain link button found at the top-left corner of most
Logic Express windows features three modes. Content Link mode is useful for situations
where multiple MIDI regions are horizontally aligned along a single track, and you are
viewing the MIDI region contents in the Piano Roll Editor, for example. In this scenario,
the Piano Roll Editor will only show the contents of the selected MIDI region. Should you
wish to view the contents of each MIDI region (selected or not) in the Piano Roll Editor
as the project plays, you will need to activate Content Catch mode.
controller MIDI data type. As examples: sliders, pedals, or standard parameters like
volume and panning. The type of command is encoded in the first data byte, the value
being sent or received is encoded in the second data byte.
control surface A hardware device that communicates with Logic Express via MIDI (or
USB, FireWire, or via a networking connection). It can be used to write automation data
and control Logic Express parameters, such as mixing levels and panning, effects and
instruments, plus transport and navigation functions, amongst others.
Controls view All Logic Express plug-ins (and Audio Units) offer a non-graphical alternative
to the Editor views of effect and instrument parameters. The Controls view is accessed
via the Controls item in the plug-in header’s View menu at the top of each plug-in window.
This view is provided to allow access to additional parameters and to use less onscreen
space.
