Alain,

I have a G-1000 which has the zip disk in it. I have not tried copying a midi file from my computer to my keyboard, but if you have a zip drive on your computer, I don't see any difference in putting the file on the zip disk or putting it on a floppy disk. If I am not mistaken, I believe the formatting of a floppy disk for a computer and the formatting of a floppy disk for the Roland is a little different. I don't know if the Roland will read a floppy disk that is formatted for your computer. I don't have my book with me, but I believe there is something in there about that. I would think that the zip disk would be the way to go, but hey, I could easily be wrong about that.
