I do have INS Definitions for the PSR 740 loaded onto Cakewalk. I did all of the things that you mentioned, and I thank you for your response. However, playback still sounds bad.

I found a way around this problem, however. Since I want to edit style chord progressions to suit my songs, I can use the PSR's sequencer to make the basic recording, and then open it in Cakewalk where I can do advanced editing. When I open the sequenced file in Cakewalk, all the instrument names come up, and it sounds identical on playback on my PSR 740. So, I found a suitable way around my problem, and making music is more important than figuring out why something doesn't work right. Thanks again.
