Editing Automation on Stereo and Multichannel Tracks
Stereo and multichannel tracks display a single automation playlist per track. Only one playlist for volume and mute is available for the stereo or multichannel track.
Plug-In Automation Playlists on Stereo and Multichannel Tracks
Some multichannel plug-ins provide a single set of automatable controls for all channels in a track. Other multichannel plug-ins and all multi-mono plug-ins provide a single set of controls for all channels when linked, or discrete controls for each channel when unlinked. See your plug-in guide for more information.
For multi-mono plug-ins, automation playlists for each individual channel can be displayed and edited when the plug-in is unlinked, and the track is in showing Automation lanes.
To view and edit the individual playlists of a multi-mono plug-in:
1 Unlink the plug-in.
2 Select the automation playlist from the Track View selector or reveal it in an Automation lane under the track.
