I need information to contact a local repair person to look at my electric piano. Middle C key is louder, sound is not correct.
Hello Baljinder, welcome to the community.
Is your piano a Behringer product? If so, I suggest that you raise a Care ticket for Service Repair explaining your problem. This is done by clicking on Support at the top of the page and then clicking the Create a Care Ticket button. This is only possible if you have completed all the required fields in your profile. Also make sure that you fill-in every required field on the Care form.
