Hello Peter,

I don't know whether you have solved your problem, but tonight I found the following in my Manual which might help and I quote:-

"You can reset all the PERFORMANCE items with the following procedure:
Turn off the power to the instrument once.
Then, while pressing the three lower left buttons in the RHYTHM GROUP section (60s & 70s, MODERN DANCE and SOUL & R&B)at the same time, turn the power on again."

Good luck!

Audrey
