My friend gave me her Clavinova CVP55 because my kids want to learn to play the piano. It worked great at first, but now the volume is way too low, even with the master volume slider set to Max. I suspect the kids were goofing around and somehow some key combination is overriding the Master Volume.
-- turning it off & on
-- unplugging & plugging
-- holding the SPLIT key and adjusting the balance
-- holding the MIDI key and adjusting the Bass volume slider
Any help would sure be appreciated! It is a beautiful instrument and we are eager to play it!
