Editing operations are not applied to members of a group that are hidden with the Track List. Mix operations (with the exception of record-enabling of tracks) are applied to hidden tracks.
Pro Tools lets you create separate groups for editing and mixing. You set this option when you use the
New Group command. Groups that apply to both editing and mixing can be decoupled.
Moving a fader of a group member causes all other group members to move relative to it. If a fader belongs to multiple groups, and the groups conflict when faders are moved, the fader will follow the top-most or “parent” group to which it belongs.
