When I started a new multitrack project just now, the Master audio timeline had disappeared.
I don't see anything under the "View" menu that would cause it to go away (or let me make it reappear).

I always assign a "soft limiter" FX to the master -- but at the moment I can't, because the master audio timeline doesn't show up in my project.
I assume I must have inadvertently entered some keystroke combination that made it go away, but can't find any clue as to what it may have been.

Anyone know how I can get it back?
Thanks in advance...
