Hello, when I downloaded the SD3 update from Ketron Italy, the filename suggests that it is release 1.0b. However, my SD3 already has 1.0b! A year ago or more, when trying to get my SD3 problem resolved, it was sent to AJ. He reinstalled the OS (which did not solve the problem). Maybe at that time he installed 1.0b, I don't know. IN ANY EVENT, either this release has been around for a year or more, or, the download filename references an older release and the name was never changed. In any event, check your SD3s to see if 1.0b is already on. Hopefully, AJ can clarify if this release is an old one or a new one with an old filename.
