. I have been using kawai CA78 for some time now. have been able to spend very less time due to busy schedule however here are some of my observation. not sure if these are standard things with kawai or issue with the one I have.

1. the entire key-bed looks a little bit tilted downward. . I have tried moving the piano to some other place but the result is same . when using a clinometer the top of piano ( music stand area) is levelled properly. while the key-bed is inclined downward.
2. when playing bass notes on higher volume the music rest vibrates and creates noise. no issue when music rest is closed . checked the screw etc.. of music rest and it seems to be tight
3. sometimes while playing sustain notes some of the notes sound are cut. bit like out of polyphony scenario.

anyone observed the same ?

The keybdd should be level. But you cannot see the keybed unless you remove some of the keys. Have you done so?

Hmmm . . .sometimes on digitals the keyboard is inclined slightly downwards, towards the fall. I rather think it looks funky . . .anmd, of course, with any acoustic, there'd be woodwork vibrations and stuff. You got lucky there, imo . . .

I would expect the keybed to be level, as I expect they would be on a piano (haven't seen one for years, much less played one). Why then, are they slanted backwards on my Roland? I mean, what's the advantage? Seems mental. I'm sure there must be a reason...just can't put my finger(!) on it.

EDIT--wait a minute...mine's a stage piano, I suppose. Is it to make them easier to play standing up!?

Because if it is, then I'm learning technique all wrong, and I'd better jack the back of my FP30 up... mad

Yes, this is perfectly normal.

Please take a look at this image of the GFII action sample (the "closest" key is pushed down, the white key behind is in the neutral position):

It's possible that another object in the same room as your piano is vibrating, or possibly even a part inside the instrument itself. Does the same issue occur when moving the piano to a different area of the room? Have you raised this topic with your Kawai dealer?

Thanks for the first point.. I can relax now smile
For the second point. the music rest is vibrating itself. when i hold music rest the vibrating sound goes away. will raise this issue with my dealer
for the third one. I will try to record the phenomenon and share.

Also any app for CA78/98 in making ? using an ipad screen rather than the integrated one will be much better.

Hello vkhandelwal, thank you for your reply, I'm happy to help.

Yes, I would definitely raise the vibration topic with your dealer.
Regarding an app for the CA98/CA78, there is currently no officially supported app, however some users have reported various levels of success using the existing Virtual Technician and Sound Museum apps with the instrument set to "Sound mode".

Kind regards,
James

James,
Please see shared videos from https://www.dropbox.com/l/scl/AACvkeBvoaGO-ca2DNF1LL20ml2e57a06cY
first one shows the sound cut phenomenon which I observe frequently. I was able to replicate that changing the mode from pianist to sound while playing.. I observe similar sound cut sometime while playing

second one has the buzz sound from the music rest. I have shared with dealer but still to receive any resolution.

regards,
Vikas

Hello Vikas,

Thank you for the update.

I'm afraid I am unable to see the video, however I am aware that the sound will cut when alternating between "Pianist mode" and "Sound mode" - this is unavoidable, due to the change in sound engine software. If the sound cut-outs during normal playing, this is not intentional and should be follow-up with the dealer.

Kind regards,
James

Hello Vikas,

Thank you for clarifying this point.

I am unable to download the video without entering an email address. However, if the video simply demonstrates that the sound cuts when alternating between Pianist mode and Sound mode, I don't believe it's necessary for me to watch.

The sound should not cut-out while playing. If this does happen, please try to make a video and seek assistance from your dealer.

Kind regards,
James

I have shared video with dealer team member and awaiting response. unfortunately i was wary of this kind of response while selecting the piano. looks like I would have to restrict myself with poor quality control and absence of support with kawai. I am in the market for another digital piano for my son and I know this time I have to go with another brand.
