It depends on what your keyboard has for a midi connection to your computer. Take a look at the back of the keyboard. You will either have the older 5 pin midi in and out connection .... or you will have the newer usb connection. The new usb connection makes life simple - just connect your keyboard to your computer and get some sequencer software on your computer to help transfer the midi data. If you have the older 5 pin connection, you need the 5 pin midi cable, and a midi to usb converter, and the sequencer software. Good luck.
