The page is fine in both Firefox and Chrome in Ubuntu 18.04. Files download fine from RightClick.

If you haven't set your browser up to play midi files then clicking the midi link will try to display the file as text, producing as you say gibberish. Neither of my browsers is set up to play midi, so if I open the midi file links in a new tab I get what you got - gibberish.

(All other links on the page - thread, DT and midi Index letters - work fine.
