Two things come to mind here.
1) Is the PC and Piano compatible?
2) If not, maybe you could download direct
to a Floppy or SD Card. Remember to
format the disk/SD card in the Piano
itself, rather than the PC, before
If your piano doesn't have a floppy drive, you can now get a stand-alone one with a USB connection at one end for around £20. They work perfectly. You can even get a little SD Card holder with a USB connection at one end. These also work perfectly. Some of our keyboard members who have the older Tyros instruments use them, but I don't know how much they are. I wouldn't think they're any more costly than the Floppy Drive.
Hope this helps.
