Hello... I just got a Roland S-50 sampler keyboard, sans any kind of operating software. I found the updated OS file, S50V20.out, however I don't know how to get the S-50 to recognize the disk I put that file on (an ordinary IBM PC 1.44 MB floppy). I've tried formatting (right term?) a blank disk using the SDISK app (from the SGroup site), and then putting the S50V20.out file on it, but to no avail. Any idea what I should try? Thanks for your time. _Kyle
