Today I tried to load some 10 tones from USB drive into my MZ-X300. Loading the last of them seemed to be extremely long, although the file was small - keyboard was frozen. After switching off and on again, no one of new and many of previously loaded and used tones could be played. Names of them are displaywed, but there is no sound. When I saved them to USB drive, those files are small and all of them end with text „UserSplit“ and some numbers (displayed in Windows Notepad). They are corrupt.
When trying to load tones, sometimes there is message Wrong Data and sometimes everything looks OK. But after displaying Complete, there is no name of tone displayed (only UserXXX) and no sound.
When trying to load rhythms, everything looks OK. But after displaying Complete, there is displayed name of rhythm, but no rhythm can be played and it is not possible to delete it, because Execute button is dimmed.
I did some testing according advice some years ago here in this forum. These are my results:
DDR RAM CHECK
DDR2 Auto
Nch:06
Pch:06
FLASH CHECK
SumChk:OK
USB ChECK
USB:NG
USB HOST CHECK
nothing displayed
RAM CHECK
RAM:OK
Can anybody tell me what happened and what to do with my keyboard?
Many thanks in advance.
