I have just used MobileSheetsPro for music to play from.  I am now faced with a situation where I do not have a pianist backing me so I need to sort out a backing track.  Can someone tell me if I can get a midi or an mp3 to play when I move to the next bit of music on the playlist or even when I want it to after I have got the music in front of me.  I am thinking I might want to comment on the music before the backing starts
