hello all... what I am trying to do is...play my tunes (midi files) from my computer (Acer),running windows 7, 64bit....to my LK230 Lighted Keyboard, through Windows Media Player....the video which I included in my original post shows a guy that has the same keyboard, using Windows Media Player to his keyboard...which is what I am trying to do...I guess I am not doing something right...as usual...I'm not that computer savy...I really don't need another on screen midi player...I have 2 now...(which don't do what I would like)...1) Virtual Midi Piano Keyboard....2) Midi Sheet Music...
