Hello!
Question on job Roland sp555.
When I switch on Sp555, are erased from card (CF Card) sempols. Sometimes completely, and sometimes partially.
Tried other memory to insert in sp555, result same
You met such errors in job of the semler?

how bout your samples on bank A and B, do they get erased as well? cause if its only the samples on your card then it might just be your card or cards.
if your loading samples from the computer onto the card then putting it in the 555 and importing them then thats another story within itself. try sampling the old fashioned way, onto a bank that uses the CF card, then turn off your machine, remove the card then put it back in, i dont know, might give you a better idea of whats going on.

i also had this same problem when i first got my sp555

the problem turned out to be the compactflash card was not compatible
i bought another one and the problem was fixed
