The whole point of a demo is to promote a product in its best light. Companies that leave their customers to figure stuff out tend to lose customers. But I guess roland have already 'figured that out'. Are not the elderly and less technically able precisely the market arrangers are aimed at ? And if the demo was for the younger market did you think the styles chosen by this demonstrator would hit the mark? Please ! Roland dont know All the customers are. No wonder their Arranger sales have suffered so terribly when Yamaha sales And korg sales continue to increase .People generate sales, technology Can enhance sales it can't make the sale .
