hi all !

I recently bought a SP-404 sampler (second hand) which was working fine, but 2 days ago, i was sampling into the memory card (from the line input), and some issues appeared :
first, when i wanted to play a sample that i recorded before, only the first ms were played,
few seconds later, every pad played the same sample as previous (only a few ms)
and finally, it basically turned off.

when i resart it, the text "sp-404" appears and then it freezes on "04", and nothing happens, but if I take off the memory card, everything works properly.

does something similar ever happens to anyone ?

any ideas about how to manage it ?

thanks for reading, and apologies if my english isn't very good...
