On my newly bought Kawai MP-11 there is one key (G6) that feels much heavier and harder to press down than the other keys, specifically it is very obvious compared to the neighboring keys when playing in that area.

Do you guys know the cause of this and most importantly the solution to this?

In a separate thread you wrote:

I would therefore raise this matter with the store. However, given that you have purchased a used display model, they may request a small service charge to inspect (and hopefully resolve) the issue.

Best of luck!

Kind regards,

Congrats job the purchase! There's not likely to be anything you can do without opening up the piano and seeing the mechanism, and I'm not sure how comfortable you are doing that with a new piano. I can never wait to pull new stuff apart but that's me.

My initial guess is that the teflon pad may have come off of the end of the key that the hammer's capstan slides against. This would increase the friction of the key press.

If your so inclined, check out the Grand Feel key clinic thread.

Even if it was a demo model, he should have some kind of warranty on it.
Opening it up by himself would void that warranty and would imho be a bad idea.

I too love taking stuff apart, so I know the temptation. laugh

They sold it to me as new with the full 2 years of warranty that is the law in Denmark and the EU and the store is a reputable one with a good reputation, so they will probably help me out. But I first wanted to hear about other people's experiences with this problem.

Well, you have the right solution then smile Unless the law is different in Denmark, a floor model sale is still a new unit, if there's anything wrong with it you should let your store know.

I haven't heard of heavy-key problems, but the Key Clinic thread is your best bet for internet information on the GF action.

Well put!

One short answer: There are lots of things inside your new MP11 to mess with.

An even shorter answer: Yes, your first stop should be back to the retail shop to get it straightened out.

If it can't be done to your satisfaction, you can then decide whether you can live with it ... but if not, opening it up prematurely would likely foreclose that possibility.

Like others posting here, I never feel complete until I've dissected and reconstructed something - especially musical gear - but in this case that should wait until after your warranty has expired.

With all those moving parts inside, there's a lot to go bonky on an acoustic-simulating action (times 88 possibilities). Kawai has a solid reputation for standing behind their gear; no doubt they'll make it right for you.

Congratulations on your new MP11 ... notwithstanding this heavy key issue, you're going to enjoy it a lot! - OneWatt
