I use a few excellent Mid files. First,I put them in Cakewalk and set the key. Then I move whatever is on channel one and set channel one for piano. Then I play piano on the keyboard along with the midi file while doing vocals. Of course I load the midi file into my hard drive on the keyboard.

If there is a better way please tell me.
