I recommend you play these Files with Chris Hills's MidiPlay, which shows the notes.
Choral Music Tutor works on any internet-capable Desktop, Tablet or Smartphone.
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.
For more about these several Players, see Playing Midi Files.
