Hi Pauline,
When I changed to the 7000 I had this problem. The way I did it was to load my 6500 data and then save to a new floppy. I then used the Tools menu on the SD card and copied the new floppy to the SD card. This way you can do 20 songs at a time.
Actually, it was a good move because it enabled me to reorganise and rename my work for various 'gigs' etc. before saving to the SD card after which, you can then make up your own 'Favourites' and 'Playlists'
Hope this helps.
Aud
