Ok, this might be a stupid question but I am a newbie with the SP555. I don't have a compact flash card for it yet but I am wondering how to save a sample to a pad so that when I switch it off, the sample is still in the bank on that pad when powered up.
Save the samples to banks A or B those two are saved in onboard memory. You'll have to disable the write protection if you want to erase any factory samples, though.
