Korg DW8000, Mono/Poly, MS-20...

Hi,

My Korg M-1 stopped reading from the memory cards all of a sudden a 
couple of months ago.

It was fine one day, I was using it ok, working from a sound I had 
saved to memory, then it just went of the card on to the internal 
sounds and it just doesn't let me go back to memory cards anymore.

I have the Canadian Korg Service center 10 min. away, so I will bring 
it in, I was just curious if someone had experienced this before.

thanks.

cheers !!

M.
