Remember:   the emphasized Files may not play properly with Windows Media Player
I recommend Session, but Chris Hills's MidiPlay, which shows the notes, is also good .
If you want a Player with PlayList facilities, I suggest either van Basco's or WinAmp .
If you're a Mac User ... you could perhaps try Roni Music's Sweet MIDI Player.
