Hi, I went to a store and tried some of yamaha digital piano P today. (I tried P60 P90 P120 P250 also pf500) And now I have a question.

I noticed that they have diffent hammer action!! However, I have read somewhere here and I believe that they should have the same action. But today I found P60 at the store has the haviest hammer action.

I have an assumption that bcause the store put P250 on the floor that many people can test it, this might make the piano keys a little bit loser than P60 which the store put it up high on shelve.

Someone told me that the key action will loose a bit after a few month of playing. But I am affraid of that. I notice that P250 in store has uneven key action. (this is not because progressive hammer action fore sure) For example some keys are tigher than the key nearby. Espcially the black keys are noticeably tighter than the white keys.

Now, I am affraid that if I got one of those. I will end up with uneven keys if I don't use all the key equally.

Can anyone give comments about this please? I ask the sale person, he is not very helpful. In fact he seems to know nothing about digital piano.

Hey,
You are right that many digital piano keys get lighter and loosy overtime. Many Yamaha digital pianos use spring to assist in firmness of the keys. Regarding key actions, different models use different model of hammer actions setup. Check out Yammy site for specific name for each model. I think you just pick the one you feel most comfortable. Newer model doesn't mean you gonna like the key action of that model. I don't think you gonna end up with uneven keys with normal use though. Just don't buy floor samples since many people already bashed them extensively and loose,wobbly keys are just not a surprise.

The technician who repaired my p250 (buzzing speaker caused by a slightly loose screw) said that the actions in the p series are all the same. But they may feel different because of the software. The p250, for example, has 3 touch settings, light, medium, heavy. Simply changing a software parameter can make it feel different because it requires more or less force to get the same sound.

no problem

Thank you for all the answers. Now, I understand a bit. Hmm, key beds are different. That is why I felt the different when playing lound, but could not feel that when playing soft.

I don't think the downweight is too havy comparing the Steinway grand piano at my university. I have played that many times a week. I am not really sure about downweight of real grand piano. Dose anyone have information about this?
