Hi Shim

You need to understand the basics of Midi before going any further, there is a good beginners guide here have a good read and you will then be able to understand the Midi implementation chart at the back of your keyboard manual. (This will determine what you can & cannot do with your keyboard)

NOTE: While Yamaha make great sounding arrangers, as a Midi controller they are not that brilliant, so you will be limited in what you can achieve.

Hope this helps
