Hello, Berhane, I don't know about how too find this exact instrument definition. There are not always instrument definitions available for a particular model. You may need to choose a generic Yamaha definition. Or you can make one yourself or have someone else make it for you. Copying my answer to the DDots-l list for others to comment.
