Bernie, Some thoughts.
1-If you put a Midi file in a folder and then add that file to your Playlist and at a later time you move the file to a different folder it will read “Error can not load”.
2-Whenever I change the key of a song in VanBasco and than press save to file I make sure that the file has the key that I have changed it to is written in the title of the song.

My reason – If I have to reboot VanBasco and somehow I have lost my Playlist, the file name will remind me of the key I changed the song to.
