I had someone around to have a look at one of my keys. Whilst the cover was off I took a couple of pictures of the innards:

Cool. Nothing like a bit of digital piano porn to spice up the forum.
Did they find out what was wrong with your key?

Its a long story.

One of the keys was making a clicking noise, so a blokey came and fixed it. He added some grease to the grey square on the bottom of the clicky key, so it now doesn't click. This is when the pictures were taken. After he left I noticed that the key is now slightly lower than the rest of the keys (it may always have been). Maybe about half the thickness of the pretend ivory. I am yet to get them to come out and fix that.

I had a similar problem with 2 keys. They didn't have the same repetition speed than the other keys. It was due to some grease on the teflon part of both of the affected keys.

Hmm. Kawai CA63 has key and firmware problems. Roland HP-307 has ringing sound. And I can't stand Yamaha's GH action. I guess I'll have to save up some bucks for an AvantGrand.

Any acoustic piano have difference in key's repetition - it is a normal (but I don't know what difference is a normal).... It is mechanic...

Avantgrand is not perfect too, if you reach the escapment point and then press firmly you won't get anysound, on the contrary of a true piano.

For the level of the key, it's just small paper circles in the central pin that have been moved in my opinion when fixing the key. It's a very simple operation to had a new one and level it.

What I see in your pics is that the grey/black square à the end of the key lever is digged, as I explained sometimes ago. I don't know what you call "clicking", but I noticed that the key can be harder to start to depress because of this.

I didn't notice any difference in having to press the key harder. The key was originally making a click noise on the return of the key. That is fixed now. We compared the key to another one that wasn't clicking, and as far we we could tell there wasn't a difference..

I'm a bit confused. Are you saying that it can't do what the Roland PHA III can?

Good to hear that Kawai service is doing a great job, also in this respect. Makes me feel relaxed, having ordered a CA93 smirk

Welcome to pianoworld, Arjan!

Where did you order your CA93? Did you order it after having played one or sight unseen?
Please update the prices paid thread on this forum.

If you live in Holland you might not get the same kind of responsive service in case of problems as in England or Germany since Holland is dependent on the German distributor. Units may have to be returned to Germany for service leaving you without an instrument for a while.

No it can't, I have tested on N2 and was surprised. I have tested PHA 3 and it can effectively do it.

That's extremely disappointing for a piano that costs over $10K. I hope Roland puts PHA III on the rest of their DPs in time for the next NAMM show.

Yeah. It is a tradition to welcome newbies on most of the forums on pianoworld, although the digital forum is the least congenial in this respect because the unofficial hostess doesn't post here much, so the rest of us have to take up the slack. Sorry we missed you before.

My Best Friend has a Kawai CP-170 and had the "CLICKING" problem with the keys he strikes most. Had a Kawai Tech come out and perform what I expect to be the same service as AndyT although the action on the CP-170 is AWA Pro I think. However, this occurred after having played for a few hours a day for about 5 years. If my CA-93 is to have the same "CLICKING" problem I sure hope it's 5 or more years down the road. For anyone who hasn't experienced this with their DP...It can be EXTREMELY annoying as I heard this on my friends' CP-170 before he had it fixed! Keeping my fingers crossed on the durability of the RM3 Action!!!!!!!!!!!!!!!!!!

While we're on the subject of newbies...

I just got my Kawai CA63 a few days ago, and so far haven't had any problems - thankfully! It's my first DP, and I have to say it's a revelation - I'm so happy with it. I'm used to accoustic uprights but wanted to play at night, and the CA63 does the job nicely.

Most new uprights need a bit of work on key return, regulation so I'm not surprised the CA63's wooden keys might need some too - I certainly think it's worth the effort.

Thanks for the pics inside, Andy - hope all your issues are resolved.

Cheers
