On second thought, I may stand corrected.
I don't have the 7000 in front of me to try, but I don't believe you can drag and drop midi files from your computer to an SD Card, and have them appear on the 7000.
I may be wrong, but the sure way is to have the midi files on a floppy and save to SD on the 7000.
