Like Jack, I found I had to save the Midi file then open it in a suitable application: in my case Sibelius, which then displays the notation as well as allowing it to be played.

To my ear, the first (multi-part) setting from the "Click to play (piano)" link has the bar (measure, for the Americans) lines in the wrong places, but that may be because a Midi file doesn't identify bars ((does it? I don't know) and Sibelius assumes that the first note in the Midi file is the first note of a bar.

More oddly, the other one starts with the bar lines in (what sound to me as) the right places, then they go wrong somewhere about bars 19 to 21. Without seeing the notation it might be less clear what's happening, but the rhythm does seem to go awry around there. I think an extra beat must have crept in.
