#1560099 - 11/18/10 09:55 AM Issue regarding Yamaha DGX 640

Hi all

I have recently purchased a Yamaha DGX 640.

I've come to notice that the DGX 640 somehow feels weird when I play it. After a while I realise that's because the black keys seems to sound louder than the white keys (i.e. they are more velocity sensitive). I've verified this by playing something, recording and exporting it to MIDI. The black keys (almost) consistently have higher velocity than the white keys.

Another issue I have is when I am playing something that involves hitting a particular note repeatedly, it seems some of the later notes turn up softer even though I am hitting with the same amount of force.

As a result of the above issues, my playing on the keyboard result in really uneven dynamics.

I have no such problems when playing on actual pianos (whether it's grand piano or upright piano). Is this a normal issue experienced by people who have not really used a digital piano with weighted keys? Will I get used to playing like these? Or is there a faulty keyboard that I have purchased?

Thanks in advance

I really doubt the black keys are different from the white except of course being taller and shorter. That may give you a little different leverage. Yamaha uses the GHS key action in the DGX640. It may be that the GHS key action does not absorb force like an acoustic action or a more expensive digital action would. The GHS keys are very light

GHS is not Yamaha's top of the line, it is what they put in their lower priced pianos. I don't think what you have is representative of all digital pianos with weighted keys.

It may take more time to learn to play on a very light action digital. Did you try Yamaha's other pianos or Roland or Kawai. They are all different

I'd suggest playing another DGX 640 to see if it's par for the course for this particular model.

If they have the same "issue," you might want to consider getting something else as you probably won't be enjoying your time with it.

DPs, as a general rule, show us where the adage "you get what you pay for" comes from. test many different actions before forking over the dough. It's better to pay a lot for something good than pay a little less and get something you're not as satisfied with.

did you play it before you bought it, at a local music store ? If so, you did not notice it there ? I personally never owned a real piano , but have owned other keyboards in the past { motif, roland D50 , etc} . My 640 plays great for my needs. I realize the action on it may be a bit lighter then a real grand piano, but I adjust quickly to such things. I have just recorded a new 4 minute piano original song, and I did not notice the black keys being louder in volume then the white keys , and this new song would be perfect for me to tell because its in the key of C# , so it has alot of black key playing involved.

I would suggest going to a music store and playing a demo unit that is already setup, to see if it feels the same way. It may be the unit you have or your own perceptions.

If the keys you are hitting are are to the left , then it is suppose to take more force to get them to play as loud as notes higher up on the piano...just like a real pianao is. This isnt a defect, it is GHS .

Im not sure if you read the manual through, but this unit has a setting where you can adjust the touch sensitivity of the keys. 4 different levels of adjustment. You may want to change that parameter and see if it helps

Hi guys

Thanks for the reply! To be clear, when I posted the question, I have played around with the different touch sensitivity, and I am also aware that lower keys are supposed to be heavier than the higher keys smile I'm hoping the problem lies with my technique in playing on this keyboard. I have no such problems playing on my acoustic piano. Hopefully in time to come I will get used to it, and be able to play silently without disturbing the people around me smile

Thanks again for the advice!!
