Kronos 88 and RH3 keyboard faulty

Yes, having the same problem. It's really annoying.

Here's a recording of me playing G2 B2 D3 B2 repeatedly, German Grand, no pedal, playing smoothly and avoiding any sudden change in attack. All the errors are coming from the Kronos.

Gets horrific around 0:55 or so (you can skip forward using the grey bar next to the play/pause button).

how long you have the Kronos 88?
I can not tell if all the Kronos have this problem or just a few ....

This sounds like there might be a problem with being able to stream the sounds from the SSD quickly enough??? It sounds like its stuttering? Sort of trying to catch up?

No, definitely not the problem.
In fact it does so with all the sounds and not just with the piano, in addition the problem, although to a lesser extent, the SV-1

maxtub - I've had mine about 10 days or so. I live in south west England but ordered my Kronos 88 from Guildford (just outside London). The units arrived at the store there in the second week of September I think.

I don't think it can be a mechanical problem or an SSD problem because in my example recording (see earlier post, above) the note pattern isn't being played quickly and the keys clearly have plenty of time to return to their original position between consecutive strikes. It's not like they're being hit when they're still on the way up, or anything like that.

maxtub - If you could name some of the voices you have encountered the problem with, I'll investigate on mine and see if I have the same issue.

The problem I have encountered on all voice and not just some, I think this may be a mechanical problem.
Try to observe exactly what happens when the key is having the problem, you'll see that has a little bounce that causes an effect like "replied" (I hope it translates well) which causes a first corrected sound velocity and a second with very low velocity

Maxtub, this problem occurs each time with different keys or the same keys?

all keys

of all buttons, whites and blacks, but mainly in the central area of the keyboard

That diagnosis can be confirmed with the MIDI sequencer.

It 'was the first thing I did
I did play the piano with a midi file of Kronos Cubase and the problem has never presented.

Wonder if there's a pattern in the serial numbers of the units having a problem...
Probably shouldn't reveal exactly what mine is, but I will say it's between 000860 and 000870. Anyone else?

mine is 00000969

Got the same problem with my Kronos 88. Also have the "clonking" problem mentioned earlier in this post thread, and posted elsewhere in the forum. Something is definitely wrong with this line of the RH3 keyboards. I've been playing a Triton Extreme 88 for over 6 years, and have never had either problem. I'm taking my Kronos back to the store tomorrow to see what can be done. Of course, that was the only in the store, so it might be another long wait to get another.

Has anyone received a response from Korg of the reason for these problems with the 73 and 88 keyboard?
I think everyone is very interested in that response. Those who received the Kronos with these defects and those who ordered and waiting to get it soon.

I'm preodered and waiting for Kronos in November in Germany. If this defect all 73 and 88 series of Kronos, perhaps i should wait until things clear up completely and dont buy it.
