Hi ,
Actually youre gonna need two things, assuming your keyboard is stereo and you want to maintain stereo to your final product. 2 female rca to male 1/4 inch adapters (2.50 each at radio shack) next youre going to need an rca y cable to a 1.8th inch (headphopne jack) this will plug into your line in on your computer. (pink jack i think)
Hope this helps !
