Yamaha NU1 Keyboard Noise

[escosa]

The keyboard of my Yamaha NU1 makes a lot of mechanical noise, i.e., clacking caused (as best as I can tell) by the hammers striking the sensors or whatever else takes the place of the strings. Seems to be the sort of noise that something equivalent to a mute bar on an acoustic piano would stop, but there doesn't seem to be a way to insert a felt strip or other thin barrier over those hammers. Noise is uniform from the lowest to the highest note/key, so not a function of uneven wear. Tried resetting, according to owner's manual, to no avail. Would be grateful for suggestions about how to alleviate.

My first thought is that the action is out of adjustment. You are correct that this can happen because of wear, but it can also happen for other reasons - e.g. - the hammer rest rail is not placed correctly.

I have been hearing this sort of thing with the N series for some time now. I think it is something that that really must be addressed by Yamaha when selling these pieces. You really have all of the disadvantages of an acoustic piano and all of the disadvantages of a digital piano and the hype used to sell these machines does not educate the consumer on what they are really buying.

Have you been in touch with your dealer yet?
