My 88 is over a year old and past warranty, My 61 was purchased in May. They both had the same internal Sanmax cards in them. I am just glad it worked for me. I have not changed the card in the 61 yet. I was waiting to make sure it solved the 88 problems first. I have only used a sustain pedal with my 61 once, so I am not sure if it has the issue, but I have a card all ready to put in if I get the issue.
When I read Woodstock0815's post. It just made sense. The piano sample is a large sample and if it was a slow or defective card, It would not be able to keep up with the read and eventually it is going to glitch. It was just horrible timing when that glitch would occur.
It is a very easy and cheap fix. Hopefully it works for you too. I am very relieved that it solved my problem.
KROME -SOUND PROBLEM

Thank you all
I bought a Korg Krome 88 two month ago. Just love it. But was a little disappointed about the Piano sounds cutting of notes with a "plop" while using the sustain pedal. Thanks to you (especially Stale) resolved everything yesterday evening. I just took his file, copied it to a new microSD using HDD Raw Copy Tool, opened the Krome, installed the new microSD and enjoyed a whole new playing experience. Funny enough, I did not have a class 10 card at home, so I used a 16GB class 4 Kodak which I had (waiting for the class 10 to arrive) to make a try if I managed to prepare the microSD in the right way.... these Sanmax cards are real bad I guess.

I just picked up a card to swap out into the Krome. I use a Apple computer. If I simply take the card out of the Krome, put it in the Apple and copy it to my desk top, insert the new card into my Apple, drag the copied file to the new card and install it into the Krome, will it work or do I need to use the raw file copier? Seems all of the info needed will be transferred. No?
I have not tried just dragging the file into the card, I used the HDD RAW Copy Tool. It was a quick and simple program to use. It took less than 5 minutes to copy. I did not time it, so I am unsure of the exact time it took.

You may not need to remove the middle ones (the ones on the grey metal) but two that are quite hidden. They nearly mad me go crazy as I was not able to remove the plastic cover. Towards the backside in the middle of the cover you will find two small arrows printed on the plastic cover. They indicate two quite hidden screws. Loose these screws and the cover will come off.
Sorry, I didn't see that this was about the Krome 88; the 73 is different (no grey metal, no arrows, nothing hidden, you just remove all the screws)...wahey wrote:You may not need to remove the middle ones (the ones on the grey metal) but two that are quite hidden.

Sound Dropping and Distorting Problem - FIXED!!!
In hopes that I might be able to help someone else through the frustrating task of repairing their Korg Krome sound issues, here is what I did that seemed to work: (General disclaimers apply - I do not take responsibility for your repair, only my own. 
BE VERY CAREFUL!! There are several areas where you risk damaging your keyboard, Micro SD Card or even your computer.
NOTE: Not a bad idea to take some good pics along the way to remember where all the screw go etc.
Needed:
- Good Philips head screwdriver
- Fast Micro SD card (I used a SanDisk Ultra Plus 16Gb)
- Windows PC
- HDD Raw Copy Software - Download Here: http://download.cnet.com/HDD-Raw-Copy-T ... ml?hlndr=1
- Micro SD Adapter (if needed for computer)
1. Disconnect all cables including power and turn keyboard upside down to access the screws on the bottom. Be careful to protect the joystick when it is upside down. I padded my keyboard stand with towels and it worked great.
2. Spend a day taking out most of the screws. (OK a little sarcasm never hurt anyone.) Do not loosen the ones on the metal bar.
3. Carefully separate the bottom from the top taking special note of the connector between the two. After you have lifted the back portion about 6 inches or so, carefully pull the connector loose to completely separate the two pieces. Set the bottom aside carfully. Pay special attention to the joystick area and right-side cover as these are especially fragile.
4. Locate the old Micro SD Card slot (near middle of keyboard)
5. Carefully slide the metal casing that surround the Micro SD card toward the front of the keyboard to unlock.
6. Once the casing is unlocked, life the end nearest the front of the keyboard to access the Micro SD Card. (Take note of the positioning of the Micro SD Card)
7. Carefully remove the old Micro SD Card.
8. Insert Micro SD Card into computer using Adapter if necessary (You will receive a message that the card needs to be format. DO NOT FORMAT!! The card does NOT use a Windows readable File Structure)
9. On a Windows PC, download and run the HDD RAW Copy Software (If prompted for permission to run, click "Yes")
10. In the "Select Device Selection" Window click the entry representing your Micro SD Card and click "Continue"
11. In the "Target Device Selection" Window double-click, "Double-click to open file"
12. Navigate to the location where you would like to temporarily store the image from the Micro SD card, give it a file name (I'll call it KromeSD for our purposes), and click "Save"
13. Make sure the file name is as expected and click "Continue"
14. Double-check Source and Target. If OK click "Start"
15. Wait until status reads "100% complete"
16. You may now exit the program by click the "X" in the upper-right of the window
17. Eject the Old Micro SD card using the appropriate method for you Operating System
18. Insert the New Micro SD card
19. Run HDD Raw Copy software again. (If prompted for permission to run, click "Yes")
20. In the Source Device Selection window double-click "Double-click to open file)
21. Navigate to KromeSD.imgc (or whatever you named the old image file) and double-click on it.
22. Check the path name in the Select Device Selection window. If correct, click "Continue"
23. In the Target Device selection window, click the item that represents the new Micro SD card and click "Continue"
24. Verify the Source and Target for the file copy and click "Start".
25. Check the target again on the Caution window and if ok, click "Yes"
26. Wait until status reads "100% complete"
27. You may now exit the program by click the "X" in the upper-right of the window
28. Eject the New Micro SD card using the appropriate method for you Operating System
29. Carefully insert the new Micro SD card into the slot on your Krome being certain that the connectors on the SD card match up with the pins on the circuit board.
30. Carefully close the metal casing and slide forward to lock
31. Carefully replace the bottom of the keyboard making sure everything lines up and you have carefully reattached the connector cable to the circuit board.
32. OPTIONAL: At this point, I carefully turned the keyboard over, reconnected cables and tested. (It might be a little safer to add a few outer screws before doing this. Either way, be very careful.
33. Once satisfied that the repair is complete, carefully reassemble with ALL the screws
34. ENJOY!

The fix
I followed these directions (compiled with others, which are slightly different) to replace the card in my Krome 76. I also had a 4g class 10 microSD card in my unit, but replaced it with a newer 16g class 10, and the fix appears to have worked. If I glissando up and down the first big piano preset, while I do run out of polyphony when doing so, the clicks, pops and crackles are gone.
The only real change I made to the process was that my computer had both and SD and microSD slots. So, I used the HDD Copy tool to just directly copy the Krome card to the new one, without copying to the computer first. I'll just save the old card in case I run across another that needs the fix.
Ribbon cables were mentioned in some posts, but the 76 did not have a ribbon. Removing all the screws on the back allowed the back to lift right off. As an aside, when placed upside down with the output jack panel side facing towards me, this allowed the best access to the card once the cover was removed.
