Walking Bass on Digital Piano

Can anyone instruct me how to set up for a "walking bass" on my Roland digital piano (KR-277)? I'm learning chords, and my music teacher suggested I use a "walking bass" for the left hand chords while I'm learning them with my right. Can't find a thing about it in the Roland manual.

Steve,
Look for anything that has to do with splitting the keyboard or Lower voice. Most Roland products have a lower voice assignment. Assign a bass sound to the lower keyboard and asign a split point.
I would suggest some type of shuffle or boogie drum beat . Something around 72 beats per minute. Good Luck .......Dano
