file -> synchronize device MusicTest (menu property)
but also see the PREVIEW (musicbee dropbox folder, 20161123-1214-sync-preview), I found how to view the devices in the left property bar (but screwed up my top view, I just can't win)
but see screen shot
no, I'm not dragging and dropping, just jsing the menu options.
AND, since I found the DEVICE tab and the PREVIEW, I used that SYNC option, still got same results
keep sending hints, I do want to get this figured out, especially since yours is working.
(I'm going out to the store with my wife, will check thread when I get back)
