Guide :Music : Full-Size Keyboard
V50 YAMAHA WITH NO PERFORMANCE SOUNDS ANY MORE
Do you know how to load the performance sounds again on this keyboard? The single sounds amd percussion work fine, but when I turn to PERFORMANCE, there is no sound and the display shows ##??!! symbols. Do I have to replace battery? Do I loose the other info if I replace the battery?
Opened it and found a 2032 sony battery soldered, is it that one?
