Hi. My question is: the yamaha Dx7 2D have internal battery? I dont have sounds patches. The keyboard on and off is perfect but in my screen said “change the battery”. I have a Kawai k-4R and i connect to keyboard whith midi, but not recive a signal. What is the problem?
when the keyboard is not used for some time, loses his memory and you have to reinstall the sounds. IS THAT CORRECT???
Hello, excuseme for my english. I have Yamaha DX7 II FD/D
I bought second hand and it has no power supply. I have seen that the input voltages are 15 and 5 volts. I have 2 red wires, 3 black, 1 blue and 1 orange. Could you tell me connections? Thank you
