Can anyone tell me if the following is possible

[Primrose Music]

Can anyone tell me if the following is possible:

Make a midi file by recording onto an electric piano's floppy disk? 
That is, are the files created in the disk drives of electric pianos 
midi files? Or not necessarily? Recommended pianos?

Put the floppy into an Imation SuperDisk Drive, linked to an iMac. Or, 
if not a SuperDisk Drive, some other external floppy drive?

Import the midi file into Sibelius? (Or any other music notation 
software programme that imports midi files)
