first you need a midi usb cable then you need a program like sonfiler. when you are ready you can download songs and samples free from internet just by googling what you need. for example type in google search basshunter midi. you will find lots of free websites such as midisite.com. when you have found the song right click it then save to commputer. then using songfiler transfer song to keyboard. thats it. good luck.
