The only way I know of is to replace the DSR1 and upgrade to the new DKC-850 Disklavier Control Unit. It adds many new features including, USB, internet & CD capabilities and a may even be able to replace your original control unit. If so, that would allow you Disklavier TV & Disklavier Radio capabilities depending on how it is hooked up. Check with your Yamaha dealer for more info.
