You can use Selection Channels to synchronize selections across multiple views. With Meter Instances, you can synchronize meters across several layouts. This means that the bus or Audio Device selected in one meter view is automatically selected in all meter views of the same instance.
You can use Selection Channels to sync views in either of the following ways:
In the Project Explorer and Event Viewer: If you have multiple instances of the Project Explorer and/or Event Viewer in different layouts, you might want these views to be synced. Choosing the same Selection Channel for multiple instances of either the Project Explorer or Event Viewer means that any selection or movement made in one instance of the view is automatically made in the other instance(s). For example, if you have three different Project Explorers in three different layouts all synced to Selection Channel 1 and you switch to the Game Syncs tab in one of the Project Explorers, all Project Explorer views synced to that channel automatically switch to the Game Syncs tab as well.

Note More than one instance of the Project Explorer or Event Viewer within the same layout cannot belong to the same Selection Channel.
In other views that include the Selection Channel icon in their title bar: Use this option to sync the view with a specific Selection Channel of the Project Explorer and/or Event Viewer. This means that any object selected in the Project Explorer or Event Viewer on that channel is automatically selected in the synced view(s).
To sync multiple instances of the Project Explorer or Event Viewer across layouts:
From the Project Explorer or Event Viewer title bar, click the Selection Channel icon.
From the shortcut menu, select one of the following options:
Pinned: To disable synchronization of the view with any channel.
Sync with Selection Channel 1: To sync the view to channel one.
Sync with Selection Channel 2: To sync the view to channel two.
Sync with Selection Channel 3: To sync the view to channel three.
Sync with Selection Channel 4: To sync the view to channel four.
To sync the Project Explorers and Event Viewers in other layouts, switch layouts and then repeat steps 1-2.
To sync other views to a particular Project Explorer or Event Viewer channel:
From the view's title bar, click the Selection Channel icon.
From the shortcut menu, select one of the following options:
Sync with Any Selection Channel: To sync the view to any channel.
Pinned: To disable synchronization of the view with any channel.
Sync with Selection Channel 1: To sync the view to channel one.
Sync with Selection Channel 2: To sync the view to channel two.
Sync with Selection Channel 3: To sync the view to channel three.
Sync with Selection Channel 4: To sync the view to channel four.
When you select an object in an Object Tab or Event Viewer, it's automatically selected in the Project Explorer of the same selection channel. To disable this automatic selection, clear Follow Object Selection.
There are three different views dedicated to metering: Audio Device Meter, Loudness Meter, and Meter. Up to four Instances (A, B, C, or D) of each of these views can be opened simultaneously within a layout. Each view of the same type within a layout must be set to a different instance. The bus or Audio Device selected in each instance is automatically synced across all views of the same instance across all layouts. The bus or Audio Device selected for a particular instance is also restored the next time you open the same Wwise project.
To sync two Meter views:
From the Wwise menu bar, click Views > Meter and select one of the following:
Meter - Instance A
Meter - Instance B
Meter - Instance C
Meter - Instance D
In the Meter view that opens, select the desired bus or Audio Device.
Switch to a different layout, then click Views > Meter and select the same meter instance from the list that you selected in step 1.
In the Meter view that opens, the bus or Audio Device automatically matches the one you selected in step 2. Subsequent changes made to the selected bus or Audio Device in either layout will be reflected in the other layout.
The above procedure could be adapted for the Audio Device Meter or Loudness Meter.
To open an unsynced (pinned) meter:
From the Wwise menu bar, click Views > Meter > Meter - New Pinned View (Ctrl+Shift+T)
In the view that opens, select the desired bus or Audio Device.
This meter will not be synced with any other meter.
Note You can open an unlimited number of pinned meters.
The above procedure could be adapted for the Audio Device Meter. You can also change the Instance of a meter view by clicking on the pin or letter (A, B, C, or D) in the view's title bar.
