What exactly do you mean by "the completed song"?
I was assuming you mean the resulting files are all named
--[project name]
but that can't be it, right? (as you don't even declare [project name] to come up in the file names)
I guess I don't really understand the issue right now, please try to explain a bit more.
But take your time, I have to run now anyway. I'll be looking back at this in a few hours. Hopefully you got your answer by then. Stay tuned
