Can I use a library from an earlier version of rekordbox for Android with rekordbox for Android (ver. 4)?
Libraries from earlier versions of rekordbox for Android can't be used with rekordbox for Android (ver. 4).
If you're using a PC/Mac, you can convert the library from a version of rekordbox for Mac/Windows earlier than ver. 6 to use with rekordbox for Mac/Windows (ver. 6).
Then you can sync it with rekordbox for Android (ver. 4).
