maggie,

Hello to you. May I ask what kind of keyboard is this? Who makes it? If it is an arranger keyboard, I would suggest that you repost your question at the arranger keyboard forum. Or depending on the actual make of the keyboard, you can repost this question at the actual manufacturer forum. If this is confusing, I would start with the arranger keyboard forum. I believe they can help you there because it seems to me it is an arranger keyboard.

Thank you for dropping by.
