576 Chapter 25 Mixing
 Same Instrument Tracks: Enable to show (or disable, to filter) Arrange window tracks
that address the same instrument channel strip. These tracks have redundant settings
for volume, pan, and so on (as they address the same channel strip), so it’s usually
unnecessary to display more than one channel strip for each track.
All View
The All view can display channel strips that don’t exist in the track list of the Arrange
area. In this situation, it’s impossible to select such tracks for recording.
To automatically create a track for a selected channel strip in the Arrange area:
m Choose Options > Create Arrange Track for Selected Channel Strip in the Mixer’s menu
bar.
This command is primarily intended for use with aux or output channel strips, which
are not usually shown in the Arrange, but may be needed for automation purposes.
Note: This function can not be used to duplicate Arrange tracks: If the selected
channel strip is already available as an Arrange track, the Arrange track will be selected,
and shown in the visible window area.
Refining the Mixer View
You can use the channel strip filter buttons to limit the display of the Mixer to
particular types of channels.
These buttons work in conjunction with the Arrange and All views discussed above.
You can use different filter button settings for both views:
 Click a button to enable or disable the view of this channel strip type.
 Option-click a button to enable it, and to disable all other buttons (all other channel
strip types).
