I know there exists a way of using terminal to back up LSDJ on a Mac though it's quite tricky. (I myself have been unable to successfully back it up that way)
There has to be an easier way if it doesn't exist yet. I wondered what kind of process would need to go into building a standalone application that you could download for Mac to be able to back up a sav file from an EMS cart. Maybe also a separate application too for Sample managing and song file managing.
Currently don't have time right now to do so though wondered what others think of the idea?
