Last night while downloading some wave tones to my keyboards we lost our power. Now I can't get the one finger chords to work at all. Sounds like only in full chord mode. I use the one finger chords. The demo songs works great but now seems like the computer is screwed. Can I erase everything and go back to the factory mode or am I going to have to get another board/ Very frustrated! Difference between the WK-3700 and WK-6500 I don't write or record music. I only play for retirement homes! Thanks for any help one can pass my way! Merry Christmas and have a safe New Year to all my keyboard friends! gary
