MusicSoft Downloader is very useful for is transferring MIDI song files directly to and from your keyboard's memory, as well as transferring Backup files and (if your keyboard has them) User files to and from your keyboard's memory, but transferring anything to and from any removable storage media can be done directly between the keyboard and the media or your computer and the media. On the other hand, your keyboard should have a menu that lets you load files from whatever external storage media (Smart Media Card or USB thumb drive) is plugged into the keyboard, so there should be no need to use the MusicSoft Downloader for that. At least, if I remember correctly, that's the way it works with USB thumb drives- the MusicSoft Downloader can't access it if it's plugged into the keyboard. I'm not sure if the MusicSoft Downloader will be able to transfer to/from a Smart Media Card while it's plugged into your keyboard- although I don't think it would have trouble if the Smart Media Card is plugged into your laptop.
