Among Yamaha's DX line of synthesizers, the DX1 is definitely the biggest and most expensive. With a dual 6-operator digital FM engine, it's like two DX7's wrapped up in a wood-paneled case and comes with a truly professional weighted 73 note keyboard sensitive to both velocity and aftertouch. The DX7 style membrane buttons have been replaced by actual push-buttons, display screens and the overall layout of buttons and diagrams is nicer and better organized.
