That’s EXACTLY what I did! This morning I got to thinking, “What a minute, what if I simply created a new project, deleted all the tracks from the new project,and then saved it as [in my case] blank_timeline?” I did that, and then I opened it up, and voila, no tracks.
So, that is what I’m doing now. I simply open my blank_timeline project to start a new project, then save the project as a different name.
Works like a charm!
