These are the limitations / flaws I identified with CA63:
1) Crackling / polyphonic flaw
--> corrected in the most current firmware!
2) Sustain test failed!
--> This definitely needs to be fixed since I can hear it on some of my songs!
3) Volume of reverb effect not adjustable.
--> It would be very nice if the effect strength would be adjustable (like it is possible for the other effects like chorus, wahwah etc.)
4) It seems that damper resonance and string resonance is still not recorded when DP is played using external MIDI data
--> Needs to be fixed!
5) No silent keypress possible. There is always a sound produced even if you press down a key extremely soft
--> Should be fixed, although not such a big deal (for me)!
6) Key off samples are very subtle, and when you hear them (with setting 10/10), not very convincing
--> not a big deal, neglectible
7) String resonance is very nice, but after pressing about 10 keys (I didn't actually count the number) in a serial order to produce resonance, the production of a string resonance sound suddenly stops. You have to raise the key and press it down again so that resonance is again working
--> This is a more academic problem, since you would only in extreme songs press so many keys to produce string resonance. Neglectible
8) Another string resonance issue: The very high notes which are not dampered at all also produce string resonance when depressed. This is not like a real acoustic, because all of these high notes should be resonate when a key is pressed, because they are not dampered all the time
--> Nice to have, but neglectible
9) I don't know if this is possible , but this would be really great: The sustain time of all keys is too short, this should be at least 25-50% longer, that would be perfect! Even better would be to have a dedicated adjustment like "sustain length" that can be adjusted from 1-10 (whereas 5 is like current setting)
--> VERY nice to have!!
CA-63 and CA-93 are not yet available in France, so I can't try them. Does anyone know if the CA-93 presents the same flaws as the CA-63 ? Has anyone tried them both side by side ?

I tried them side by side but did not check for these flaws. But I guess they have exactly the same firmware built in except for some additional sounds of CA-93. Everything else is 100% identical.

Has anyone been able to compare the CA93 version of the RM3 keyboard with escapement next to the HP-307 versus the CA63 version without?

Yes, I did. See my dedicated thread for this specific comparison.
Im not too much used to escapement because I'm mostly playing acoustic uprights. So the additional escapement of CA93 is not a big deal for me when comparing both of them, but it's noticeable when you play very softly.
Generally I clearly prefer the action of the CA series.

There are a number of complaints that come up from time to time after people have used their digital instruments for a while. These include:
- hard bottoming out of the key motion causing pain and repeated stress injury
- keyboard becoming loose or irregular
- keys becoming very noisy and disruptive for other people
- keys becoming sluggish or less responsive
- long exposure to sound leading to evaluation of sound becoming artificial or dead sounding
- irritating ringing or harsh sound, particularly individual notes or mid-section making practice annoying
- pedaling and polyphony not acting authentically
It would be very interesting getting any feedback from Yamaha CLP & AG, Kawai CA and Roland HP users if they have experienced or are experiencing such issues.

- oh yes, my CA63 does that (so I suspect the CA93 does too), see this thread: https://www.pianoworld.com/forum/ubb...r%20Kawai%20CA63%20owne.html#Post1387821I've come to get used to it, though every now and again it still stops me in my tracks.

Question for those familiar with both the Kawai and the Roland:
Is my understanding correct that the Kawai lets you record directly to USB both MIDI and MP3/WAV while the Roland does not?

It is my understanding that Kawai CA63 and CA93 records MIDI internally and that it is able to render MIDI to MP3 after the recording was finished.
Now Kawai normally doesnt use string resonances while playing from MIDI or from the internal recorder.
So it is also interesting if string resonances will be rendered to WAV or to MP3.

CA63/CA93: You can play live and immediately record it to USB in both MP3 and WAV format. All effects will be recorded (WYHIWYR = what you hear is what you record).

Thanks for the information.
So far I can see from the manual it asks: "Save to USB?" when the recording is finished.
So if it records WAV and if it saves afterwards then it must have a lot of internal storage. How much is this? What is the limit of recording capacity?

I already recorded a WAV file with more than 30 minutes length, I don't think it has that much internal storage capacity, so I guess it stores to USB stick already during recording. But at the end of the recording it asks if you would like to keep the recording, and what name you wnat to choose, so this is more like a finalization or a deletion of the already stored piece.
There is also not much difference in storing duration regardless of what you answer to the question "save to USB Y/N?".

Can anyone confirm that what Kawaian confirmed for the Kawai is NOT possible on the Roland?

Yes, kawaian is correct. The MP3/WAV recorder saves the audio to a temporary file on the USB device, which is then (re)named accordingly following the user's input.
With the current software it is not possible to convert a MIDI file to WAV/MP3, however songs stored in the internal recorder (i.e. user songs) can be converted.
Cheers,
James

James, to be more precise, it's not possible to store the MIDI data that is received by MIDI-In directly to an MP3/WAV.
