Hello ,
You may want to play with the EQ a little . If you have an X1 with the hard drive then there are more piano sounds stored in folder #1 . There are also more pianos under the user voice as well as bank 1 and 2 . Have you received any of the super solo's ? These are even more improved paino sounds as well . I haven't had any complaints about noise . Make sure your using good cables . Many people buy a $2500 to $3000.00 keyboard and then use a $10.00 cable . Good Luck Dan O
