Yes you can, into internal memory, but better yet..get a pc card[external memory]..
All you need to do is connect the USB cable to the E80 and PC..Go into menu and select USB..there you make the connection to either internal or external..

Copy SMF's to the folder that says "put new songs here"...like wise you can add styles to "put new styles here"..

Any help you may need ..email me..
