I have a DGC1M4 disklavier and I think it's not possible ( )
Orlando,It wasn't a mistake and it is actually quite easy to do. I don't have a handheld controller in front of me, but if you call your dealer where you purchased it, they should be able to walk you through it over the phone. If they can't, ask your salesman to come out to your house and give you a little lesson. I'm a Yamaha dealer and we do this all the time for customers, so don't hesitate to ask.If you can't get the answers you want from your dealer, call the Yamaha tech support. The number is 1-800-PRO-YAMAHA (just leave off the H A).
