For Studio One 5, the menu that includes Tune and other options under Inspector won't be readily available If you merged (edited) tracks before using Tune, Instead you will have to select all of your copied tracks in the New folder you made, and then Bounce them by hitting CTRL + B. After the rendering process the menu that includes Tune will now be available. After you tuned to your desired settings you may have to bounce those same tracks again if you are getting those little cogs icons on the copied tracks.
