Problem with my 9000: awful disharmonics in the styles(sounds like a german ambulance-car)....and it is ONLY in certain Registrations.The same styles are ok in other registrations.And it concerns Em,C,Am........but not D and G.
I checked nearly every parameter in those registrationsn and did not find anything (Fingering is ok).
Hi Ralf, I've only noticed this problem with sus chords if you play the wrong inversion. What fingering mode are you using? Is it one of Yamaha's styles and registrations or one of your own?
