Using Advanced Selection Commands
You can make moving and copying tasks faster and easier by using the selection
commands outlined below.
• Selecting All Used Instruments: The Edit > Select Used Instruments function selects all
objects that are assigned to the selected track in the Arrange window (or tracks that
contain regions), or are connected to such objects via cables.
• Selecting All Unused Instruments: The Edit > Select Unused Instruments function selects
all objects that are neither used in the Arrange window (as tracks which contain regions),
nor connected to any such objects via cables.
• Selecting Cable Destination or Origin Objects: The Edit > Select Cable Destination
command highlights the destination object of a selected cable connection. This is
particularly useful in two cases:
• The destination object is on a different layer. You can use the function to select and
display the destination object (and layer).
• When in the list display (View > By Text), you can locate the destination object of a
source object, because selecting the source object also selects its cable connections.
This function allows you to follow the cabling from one (serially cabled) object to the
next. If several objects are connected in parallel, or several cable connections are
selected, the path of the top cable is followed.
The Edit > Select Cable Origin command essentially performs the reverse task, where
the MIDI signal flow is back-tracked to the source (or origin) object. This is particularly
useful for troubleshooting, or when you want to make changes to a number of serially
cabled objects (by changing the original).
• Toggling Your Selection: Just as in the Arrange window and editors, you can change
the status of any selected objects in the current layer by choosing Edit > Toggle
Selection.
Creating Your MIDI Signal Path
Before any MIDI events received at your computer’s MIDI inputs can be recorded by
Logic Pro, there must be a connection between two Environment objects:
• Physical Input object: This represents the MIDI In port(s) of your MIDI interface.
