Good morning -I have a Portable Grand GSX 630.I've noticed that in any octave throughout the keys when I play a G and try playing a C above it at the same time, nothing happens -all I get is the G. As noted this happens on every octave for the same corresponding keys.
Can you help
Many thanks

Hello, my name is Rusty. This is a serious problem with your tone generator. You're going to need a hands on expert to do the repair, what is your postal code?

Hi I'm at SA3 5DH in Swansea

Ok, Yamaha has service centers all over, you'll need to call them to find the nearest repair facility. It's not going to be an expensive repair, but it is very technical. Call 0844(###) ###-####
