Hi Rich,
the gain levels are saved in the project, there's no need to mix and render
first.

So if you change the gain on a track in a project and then save the
project with the normal control-s keystroke, is the new gain level saved
or must you invoke that mix and render first? If it is the latter, I
guess you will be creating an excess of material in the data folder.
