Thank you for your reply. I have tried to create a registration again without success. The PX350 is a fantastic Piano although I would like to play it chord / Keyboard style. The internal preset styles are very good although when starting them there is a 'fixed' chord progression included. The manual says play the melody line along with them. Whilst it is obvious with some of the presets what the song is, there isn't a songbook built in or a hard copy. I would be happy to use the presets and then try to save them as a registration, however I am unable to turn off the chord progression ! Im finding all this very frustrating.
