I have a mz-n520 net recorder and i have got sonic stage running with windows 10. You need to disable driver signature enforcement when the computer boots up then you can install the unsigned md driver other wise the pc wont reconise the md recorder and sonicstage wont see the md recorder either. Took me a while to suss it out through trial and error lol. The drivers and sonicstage are available here in the download section.
