well heres some more info ,,
the music player has to do the same thing ,,have to refresh the media in the player ,, its about 1300 songs in the 32 gig sd drive ,,the media player see only about 60 then i have to scan for media for the rest,,takes about 4-5 min ,, yesterday when opened tablet had to do this ,, then went to the Cross DJ pro app and went to load song in player ,,all 1220 files there but no bpm listed and usually leave it in bpm /songs view as to just randomly pick song either in a progression or de gression order ,, so hence the need for re anyalising the collection,, about two hours,,so much for just having a tablet to carry for a adlib mixing session ,, untill figure this out ,,dont think this is a Cross app issue ,,as to the same thing happens to the media player/music app ,, gonna see what song are left in the media player to see what maybe is the difference between the tracks there and the one not there ,since all the files where loaded to the sd drive ,,except one
