Hi,
I don't know the specs of your keyboard, but there are two possible ways.
If your keyboard is equipped with a floppy drive, you copy the roland styles at your PC to the floppy, eject and insert to keyboard.
If your keyboard is equipped with a media card slot, you need a card reader (very cheap 10 or 20 $). Plug this reader to USB, install driver, if needed and insert a blank card.
You can use the card reader as a usual drive, copy the roland styles to the card, eject and insert to keyboard.
Refer to keyboard's manual.
And if you can't find a solution write an eMail to Roland or call the hotline.
