unfortunately my sd1 behaves more like Toni's. Rikki, what's your secret for a healthy sd1? how old is yours? what OS and EPROM? how many mbytes of samples do you load on start up?
mine is an old sd1 (not plus)with some buttons need to be cleaned but they all work, os 4.0c, eprom release 4.2 (ordered from AJ the new release, hope that will help), and I use about half of the memory with my favorite samples.
