Just today I asked the staff of my Hong Kong retailer to bring in a new Kronos 73 from their warehouse for me to test. After opening the box personally it loaded into OS 1.5.2
I tested the keybed for a good hour and had no audible cut off or double striking problems at various velocities. I also spent some time playing pp lines across the whole board with no obvious problems.
The keybed was relatively evenly spaced. There are obvious extra gaps between E3/F3 and E5/5, otherwise it seems pretty consistent.
With this in mind, what are your thoughts moving forward ? **
** I had one problem with the particular board I played - on the new german piano patch (across all variations of it) I had found that the the F3 key had to be played harder to get the same response than other keys. I would say 15-20 % difference. However, when moving to other patches that did not include the german piano this was not the case. I don't believe this to be an action issue as is only happened on German Grand patches. Is there any info on this to add ?
Thankyou in advance... |
What was the serial #? Although not conclusive, the serial number along with your other observations might give you the comfort you need.
There are plenty of reports of the cutoff issue appearing over time, or only under certain conditions. Given that you have very little room for doubt on the matter, I would at least make sure your unit has a relatively high serial #. |
Thanks Bruce, I know you are well versed on this issue. Does the fact it comes out of the box as 1.5.2, which is supposably the OS revision for the new keybed, provide you any comfort ??

Yes, because 1.5.2 was only supposed to be for the updated keybed. But to be frank, my experience with this issue and Korg has been so poor, that I would only want one of the more recently manufactured units.
And since you gig... Don't forget to keep the cardboard spacers and use them every time you move the unit.

It's the rubber compound which is faulty, causing the double trigger etc. mines on its way back to Korg on Saturday.

On Friday, April 6, I drove 2 hours to Westminster, MD to have my K73 keybed fixed. Turned out that the shop had the wrong parts and had to order the correct ones. Since he had a service call in my area, he promised to repair my instrument on site when the parts came in.
Today, Geoff from Amps & More did the fix. The new rubber switches are blue instead of pink. He also made sure my keybed was back from the support rail so none of the keys thunk.
We tested it out, all is good.
Knowing how long it takes to ramp up production on parts, especially if they're dealing with parts suppliers, and adding in the time to took to test for the problem, I think Korg's response was very timely on this. The instant response nature of the Internet made this seem worse than it really was, in my opinion.
I know many of you are living in distant regions. I think the lesson learned is to wait until a new product is out for a year before you leap if getting it to a repair shop is a hardship for you. It shouldn't be that way, but that's the nature of today's market. |

| I've been working with Advanced Musical Electronics in LA to get my Kronos repaired. They also let me know that Korg has switched to send out new contacts for the keyboard. This is much more labor intensive for the service center. And the parts are backordered. |

It is hardly more labor intensive than swapping out the actual keybed. In fact, I would expect that swapping the switches would be faster and easier. I watched the tech do it. The entire procedure took less than 20 minutes.
The switches come in strips of several keys. One strip is lifted out, the new one is laid its place. On the 73, he had to cut the strips on each end to fit the number of keys. Seriously, it was quick and simple. |

Hi everybody! I am Nam, jazz pianist from Hanoi, Vietnam. I just bought my Kronos 88 2 weeks ago in US. My "Keybeb RH3 from Japan" its display on highest C . Then i found the problem is playing piano and all another sound , the cutoff sound appear when i play softly. I update to OS 1.6 already.
I have read all your complain about cutoff and keybeb problem, it seems my RH3 is newest update keybeb from Korg isn't it ?
So the question is : OS 1.6 + Newest Keybeb = Still cutoff problem?
Or do i have to return to OS 1.5 to fit the Keyboard.
How to make OS 1.5.2
Anyone can help me?
Thank you

AFAIK OS 1.6 supports the new keybed which you might not have or at least not the fix. I assume you also contacted Korg Support? They can fix it for free.

My understanding is that there is no "new keybed," only new switch strips under the keys.
OS 1.5.2 only added diagnostics for service techs, no new user functionality. 1.5.2 is only available to service centers and adds nothing the end user needs.
OS 1.6 is needed for the Editor software and certain new sound libraries. |

Hi all,
My new kronos 73 has arrived and I am trying to get it to display the symptoms of this keybed problem. But I cannot ...
Can someone explain EXACTLY what it is I need to do to test the keybed on the Kronos?
Or is it a fault that appears with time and use?
OR is it simply that not ALL keybeds are affected?
Thanks |

Dan! It looks like you are based in Southern California! You should work for Advanced Musical Electronics. They told me it would be much more labor intensive, and the manager was actually negotiating with Korg over the payment for doing this "more labor intensive" service. Can you call Advanced Musical Electronics and explain to them what they do not understand about repairing the Kronos?!? Where did you have your work done? |

Sorry, Friend, I'm in Pennsylvania. I had the work done by a shop in Westminster, MD. Not sure what makes AME think this is so tough.
I'm a little skittish about tearing open equipment, but having watched this fix being done, I think I could do it. Certainly anyone who has swapped memory cards or circuit boards could do it. |

1. When and where fixed.
19 April South Pacific Music New Zealand
2. Which model.
K73
3. Information about specific repair.
Keybed replaced. Version 1.6 installed.
4. Results. Did it fix the problem.
It is a complete success.
5. Serial number.
000855
Helpful, knowledgeable and friendly service tech.
Installed 1 Gig ram I supplied. My keybed ordered 2 months ago and had to wait for consolidated container order, and shipping port strikes here locally. Technician also got sent a set of blue contacts that had been sent for another Kronos 88. He had been told this was latest solution to repair faulty keybeds
In practice, the notes now trigger earlier than old keybeds. I prefer this new action and it feels less spongy. No regrets buying this Kronos. Go buy one now yourself.
