I consider this a positive feature, actually. My piano doesn't need a clock to function.

I didn't mean a date/time that controls the piano. Just date/time for the USB timestamp. I wouldn't be too concerned about daylight saving time changes - standard time or even UTC would be OK. Just not 11/30/2003 11:00PM for each an every file. That leaves no way to sort files.

I tried to revise my previous post but it timed out and could not be changed. So please ignore it.

If USB timestamps are not important you don't have to set anything. You are correct - unplugging would require resetting the time if you want correct timestamps. This is not a portable piano so disconnecting from power is most likely a rare event. In most cases it would always be connected to power (unless there is a power outage which occurs very very infrequently in my case). I wouldn't be too concerned about daylight saving time changes - standard time or even UTC would be OK. Just not 11/30/2003 11:00PM for each an every file. That leaves no way to sort files.

Is this a big deal? No, but surely a relatively easy to implement improvement. Not nearly as important as my previous post about the Wall EQ.

You should be able to make the WallEQ setting sticky by using the "startup with favorite" option.

Just found it now. It works great. Thanks for the input.

Bumped into a bug the other day, if it’s been mentioned already I apologize.

When switching from sound mode having played something other than piano - something bell like, I don’t remember - to pianist mode, the bell sound was still played in the background when releasing a key. A restart of the unit fixed the issue.

The Kawai leadership team needs to make a trip to the Carnegie Mellon University and take some lessons on quality and on development methodology.

Thank you for bringing this to my attention.

This bug sounds a little like this issue, fixed in the most recent v1.0.2g software update:

Quote
- Fixed: Electric Piano key-off noise could stop sounding in some cases


If you have not done so already, may I ask you to update your CA98 to the most recent system software (available from the Kawai Global website) and check if this issue still occurs, please?

Kind regards,
James

The Kawai team should look on how the GUI software is interacting with the sound engine when switching between sound and pianist mode. It sounds like the DSP filters (e.g. ambiance, reverb, EQ,... ) and/or the resonance model and/or audio pipeline are not being properly reset when the switch takes place. There might be a conflict (or race condition) between the messages being sent by the GUI software and the messages being handled by the system software. Or the issue may be unrelated to the GUI and derived from how system software is handling the switch between pianist and sound mode.

I also believe that the underlying issue is independent of the instrument. For example, this weekend I experienced a similar situation after switching from an harpsichord to pianist mode, and this was after the update to 1.02g . This bug happens occasionally (but not consistently) when switching between sound and pianist mode favourites and I have commented about it several months ago. The same outcome may also be experienced after the DP receives MIDI in messages from an external VST in pianist mode. In both cases, a restart is required to reset the sound generation in pianist mode. I am not sure how a end-user can help Kawai finding the underlying problem since this cannot be consistently replicated...

Sorry, by "similar situation" what are you referring to, please?
Are you saying that (like iLogic above) you experienced a situation whereby switching from "Sound mode" Harpsichord to "Pianist mode" SK-EX Piano, you could still hear the harpsichord's key-off sounds?

Kind regards,
James

I am referring to the non-systematic issue that happens when changing from a sound mode instrument to the SK-EX piano in pianist mode. When the problem happens, the sound in pianist mode becomes "wrong": it sounds the like the sound engine was not reset after entering pianist mode. You can perform the following test:
1 - Go to pianist mode: select e.g. rich or full character in pianist mode, increase resonance and ambiance to create a distinctive SK-EX sound.
2 - Go to sound mode: pick any instrument (I suggest any non-piano instrument).
3 - Repeatedly play a note e.g. C4 at a moderately fast tempo. Continue repeating this note for the rest of the test.
4 - Select pianist mode. Listen to the sound of the note.
5 - Select sound mode for a few seconds.
6 - Switch back to pianist mode and continue repeating the note. Listen very carefully to the sound. Almost immediately after selecting pianist mode, the sound engine starts producing a piano tone. However, you can hear that the settings will only be fully applied after a short moment (maybe 0.5 seconds). After that, the generated sound will be exactly the same as it was in step 1 or 4. This is the expected behaviour.

The issue I have experienced (several times) is that after switching from sound mode to pianist mode, the sound output in pianist mode will remain like you hear on those 0.5 seconds immediately after the switch. Switching back and forth between the modes sometimes sorts out the problem and resets the sound, but usually it requires a restart.

Hello arc7urus,

Thank you for the additional information.

I no longer have access to a CAx8 in this office, but will pass on your feedback to my colleagues in R&D.

May I ask if you are able to record this phenomenon happening, please?
Of course, it will not be possible to use the built-in USB Audio recorder, however perhaps you would be willing to shoot a video on your phone?

Kind regards,
James

UK, dealer is Rose Morris in London.
Repair: WDO Green (if I have spelt it correctly)


So Nigel came to visit the piano.
Unfortunately he was not aware of the issue and could not fix it. (The LCD crash when headphones are connected)
He opened the LCD screen and checked the connections, but nothing more.

The problem reappeared again (seems to get worse as the time passes).

Tried to contact the company WD Green and they clearly told me the do not want to talk to me. I have to go back to the dealer.

Now, another visit is completely useless, until Kawai propagates all these instructions to all repair companies.

Nigel told me he knows you Kawai James and would check exactly what the issue is.

I find this process extremely complicated: Contact the dealer, dealer contacts service company, someone comes.
Result, information has been lost at each step.

If I could contact directly someone in the know, we would save useless trips.

Any suggestions?

When I needed service the first time I contacted the selling dealer. He gave me the name of a local repair company.
I dealt with that company only ... Adam's Organs in South Florida.

If there were any dealings with Yamaha concerning the warranty he dealt with that.

Regarding my problems, the only parties were Adam's and me. Simple.
No information could be lost in that chain of communication because there were only two parties in the chain.
I like simplicity.

I'd like to see if my piano needs updated. Is there a way to see which letter version it is currently running?
