I've recently been using my Roland E-300 and can't figure how to change the styles that I'm showing in the diagram ("panel descriptions...music styles" in the manual). Can anyone guess how to change from the "top row" to the "bottom row" (ballad, waltz, swing etc). Right now, luckily, I'm accessing the styles in the "top" row.

I was able to do this years ago, but I can't remember "how." The manual doesn't explain it either.

Anyone have any guesses on what to do (IF it's not broke)?
