Kronos 2 88 : keyboard velocity curve

Post by Erwin_W »

Sorry Korg , these velocity ranges are strange ??

- velocity 9 or 4 , you can't reach the higher velocitys with normal piano playing ?
- velocity 5 , ok ... but then you don't reach the lowest velocitys
???

As a tests I connected my Roland Fantom X8 as a midikeybed to the new kronos 2, and this plays ok - the piano sound is now .. 'open , nice and clear'

Can somebody comment is this is normal or maybe there's something wrong witjh my Kronos 2 88 keybed ?

Piano velocities can vary depending on which one is being used.
The number 5 should provide constant ones,usually for organ or similar voices etc.
The number 9 is the best for pianos,but some prefer a lower setting.

The SGX pianos have several settings available that can alter velocity responses,(velocity bias and intensity)but there isn't a set rule and some experimentation is required.
Try a google search....eg-"kronos velocity settings",it may bring up a previous posts on the subject,there are other post that have some suggestions as well,which is interesting reading.(There are a number of them....).

A simple keyboard test would be with other pianos,HD etc.....this could show any physical abnormality,if any.

I've had velocity problems on some keys with my own K73,but only with the German piano voice.....the Japanese and all other voices play fine.
It was initially thought there was a problem with the keybed,but despite several repair attempts that included two sets of rubber contact replacement and a whole new keybed.....it didn't cure the cause.
The final verdict being that it's a characteristic attribute of a Kronos German piano to play in that way......and other Kronos instruments are the same.

Following the fourth repair attempt and the given statement by Korg UK,I finally gave up seeking a cure.
However,despite this,I must say that the service I received was excellent.

Also,further tweaking of the Japanese pianos have produced an acceptable set to my liking and they all play correctly,so,all that I'm "missing out" on are the German pianos,which now have an alternative instead.
Although I've not actually measured the velocity levels accurately,there is some indication that they do vary,not only during normal playing as expected,but also during"controlled" key presses.....with a failure in replicating the same velocity levels each time.
This variation is evident using the "book" method as well.
"Book" method is using a straight edge(a hard-book edge,for example or something else,suitable) to press keys down together in a controlled manner....crude,but effective for testing purposes.

Perhaps the better approach could be to listen to the response,rather than visual velocity indicator levels.
Meaning that if it sounds ok,it need not be of much concern.
However,if the key presses don't play correctly,then there could be a fault.....the usual culprit being the key rubber contacts.

Hope this helps.

Best Wishes.

Thanks for your reply pedro !

I found some more info in other threats for earlier kronos version.

As I did a new test with combi , and put velocity zones to 124-127.... I'm not able to hear any tone , not witch curve 4 , 5 nor 9 :-/


As this 'mal function' is in since first version of Kronos , it feels like this is how korg is implementing it , and don't care about this :-/

Damm !!

It seems some Kronos have keybeds that produce high velocity easily while some don't.

On my 88 is very hard to get above velocity 110, maybe yours is similar. Mine got sent back to Korg and they returned it saying it was normal, I think they tested it with a hammer!

Without any intention of making derogatory remarks about Korg UK,….I'm of the opinion that their biggest failing point was with initial diagnosis and subsequent testing of my Kronos that needed attention.
I doubt whether they even played the keyboard during any repair attempt.
Pressing a few keys to confirm they make a sound(isn't the same as actually playing) can present a false impression that all is well.

I was sent some test results about my keyboard,which made no sense at all.
The method used just showed that the keys produced some velocity response,but overlooked their inconsistency values and they concluded there wasn't a fault.
I had previously provided some evidence that could have helped to indicate my problem,but it seemed to have been disregarded by the technician.
It was only when their senior demonstrator actually played my keyboard it became apparent there was a problem….but as said,they concluded that it's a "characteristic" of the Kronos RH3 and most are the same.

This is total nonsense of course,but there's nothing further that can be done about it,in my case and I have accepted the loss of just one SGX set of pianos.

There have been many posts regarding different facets of keybed problems…..note cut-off,note re-trigger,max velocity levels and as in my case inconsistent velocity levels.
Some owners have had successful repairs…..rubber contact replacement etc,while others have not.

At this stage I'm trying to avoid entering into another long winded posting about this subject...I wouldn't mind,but perhaps other forum members could object to a rekindling of the matter,again.

My view is that the actually velocity levels themselves are not that important as long as there are consistency along the whole keybed and the voices sound ok.
However,if they don't,I can only suggest that you contact your local Korg support for further advice.

Also,do try different settings with the SGX pianos,as previously suggested.
The only link I can find with some examples is…..

There are more,but can't locate them at the moment.

Please do return here for further help and any comments you wish to make etc.

Best Wishes.


Edit.
Another link that could be of interest...if you have the time to read a lot.....:wink:

Thanks for the replies.

Although, I don't see why this should be a long winding post ?

or

1) there are persons in this nice forum able to reach velocity 127 (with a 88 key RH3) , with velocity curve 4,5, or 9 -> in that case my Kronos 2 88 keybed is faulty. And maybe it needs to be calibrated ? as I red in some posts.

or

2) Noone can reach velocity 127, and the implementation of Korg is what it is and wurthless in t he same time !

Just trying to find a decent piano / which will cutt through the mix in a coverband situation (no candle light stuff ;-) )

I can reach 127 on my 88, but it requires a pounding. I believe that is the way it should be - 127 should be the absolute maximum, not "pretty hard". E.g. I max out my RD170 all the time even on the "heavy" curve, which sucks. I should say that I'm used to playing real grands and pianos, and my touch is pretty dynamic. So for me the Kronos feels fine. I can't say how I'd feel playing your Kronos though ;)

Btw I'd really like some user calibration though. Two or three user adjustable curves where you first play a few notes as soft as you can and then as loud as you can and then have two or three curve points to adjust would be my dream.

Just a suggestion for tweaking the SGX piano.

Try using the stereo exciter/enhancer and compressor fx,with eq to suit.

Also adjust the velocity bias and intensity.

An useful link....

I use velocity bias +035 and velocity intensity +045 on a Japanese piano,but it's a matter of preference.

So, does kronos 2 have the same issue ???

Man let me share my little story, I just bought a 2ndhand Roland Bk 3. It was so cheap on ebay. Bought it just to lug around teaching at different schools.
Ok yesterday I tried the unavoidable. Connected Midi with my kronos and played it roland. The roland bk-3 keybed has smaller keyes than kronos and is NOT hammer action just another synth keybed........to my surprise ......Mamamia here I go again.
I couldn't believe my roland with toy keys made my kronos speak all velocities and the high velocities and the release was short and sweet.

Of coarse some will say, well just use the Kronos with a controller...but Helooo The Roland bk-3 is not a controlor and Should not be better than the kronos how come it makes the sounds speak their full voice??
And please don't come up with the excuse that..oh maybe you should adjust the velocities parameters insed the german japanes etc. I will answer I've tweaked my hair out on those . But the point is ....why on earth a keyboard that costs a fraction of a kronos can reach all velocities out of the box ( connected through via Midi) ?????

In fact when I did that I had to go to the Kronos and zero the velocity bias on the piano for it to play as it was meant to be. pp,p,m.f.ff

I will be recording a short video showing the differences in sound just to clarify
