Very strange behavior means "not like I expected with Logic Pro X".
I think it all behaves in a "rational" way, but that doesn't mean the way I expected.
Simply put - Save As - when making a new song - gives you a decent starting point.
I don't know what to expect. Trying to gauge behavior with expectation.
I think it works just fine, as long as I understand what is being saved and where can I expect to find myself when I recall saved versions of things.
Not trying to make it complicated
