Maybe some one on the list could give me a helping hand. I have ablind friend in another state who just perchase a Yamaha psrs910 keyboard. I would like to know the layout of the button controls on the psrs910. I am a Tyros4 owner and maybe I'll be lucky that the button layout is some what the same as the t4. Once I understand the location of the button controls, I can help my friend in learning the keyboard. Email me off list. jmkeybd1@xxxxxxxxxxx Thanks.
