I am trying to save just a portion or "clip" of a song. I insert new track before and at end of portion I want to clip. How do I save the new tracks, while still preserving the original song? Do I "Save project" or "Save file" Don't understand the difference. When I save anything the original song disappears, and all I have is the clip. Would like to save both the original song and the new clip. Thanks MK
