The selection arrow is dark when I choose a built-in rhythm pattern. When the song recorder button is lit or flashing, the arrow is no longer dark. The rhythm pattern does not produce a sound when I start to record. There are no recording problems when I choose a sound from the tone list. The selection arrow always remains dark. I don' t know if I pressed some wrong buttons, but the problem is not corrected even after turning off the power. I am just trying to figure out why the selection arrow for the rhythm choices goes from dark to light when I try to record a pattern. I would greatly appreciate any help.
