Thank you everyone, all of you were right. It was not a problem with my
midi file, just with what I was reading it with. I was trying to read it
with timidity, but I am indeed missing packages / sound fonts, and my midi
file is read fine on another computer. Since it was also the first time I
was trying to generate a midi file, I ended up thinking it was my code, and
not the player. Thank you as well for the people who explained to me how to
interpret what timidity prints out in the terminal (I definitely wasn't
interpreting it right ^^).
