Bonjour,

Les craquements sont un problème connu sur les Kromes ( j'en ai un), il faut changer la carte micro SD interne du Krome avec l'image disque, si vous voulez j'ai une copie de cette image, la personne qui m'a vendu le Krome avait changé la carte sur mon Krome..

J'ai trois Krome 88 et les craquements sont sur un seul... (sur les sons EP principalement). La manip résout ce problème ? où trouver l'image? Merci de ta réponse.

Krome sd card fix

The process is very straight forward. It is documented step by step in this thread. You are copying your files to a new card and I put a link to the clean working copy. You will still have your old card if you were not happy with the results. It is very simple.

Here is rhall's very detailed description.

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. Wink

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: https://download.cnet.com/HDD-Raw-Copy-Tool/3001-2094_4-75544749.html?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 Smile
34. ENJOY!

PS: If you want to short-cut steps 10-17, you may download my image file. I won't promise how long I can afford the space to keep it online, but at least for now, it is at: http://bit.ly/1VGTb5U

Also I posted a link with the image file as well It can be copied from here.

You can just load my image on the new card and replace it with the original card

This is very simple and worked on 2 different Krome's for me.

Korg Krome piano sound problem - resolved
Hello,

A message to deeply thank 'Stale' who wrote a complete procedure on Tue Dec 08, 2015 5:21 pm to build and replace the unsufficient factory MicroSD card on Korg Krome.
I followed the procedure using a SanDisk 16GB Ultra microSD Class 10/UHS-1 (it ony costs 10 Euro in France, it is the same as the one cited on a recent post from another user who reminds us that it is also known as SDHC) and it works perfectly well: the big noise happening sometimes from the OSC2 resonance and which is quite documented on this forum or on Youtube, completely disappears when playing on the Krome keyboard (a Krome 61).
Note that it doesnt solve completely what might be computing or I/O capacity limits: I still have very reduced noise surges when the piano sound is heavily treated by IFX effects or when playing heavy chords with damper from an external midi keyboard.
Last information: I used the HDD Raw Copy Software which works fine even on a 64bits Windows 10 simple laptop but it needs reboot after installation. You must have administrative rights for HDD Raw Copy to run properly and be cautious!!, this software may be a dangerous computer administration tool.
Hoping this post may help.
Etienne
