Cannot open MIDI file
I downloaded a bunch of MIDI filles from the pianoadventures.com website to accompany my book, and they will not open in MuseScore. I get an error saying: "Load failed: bad midifile: MThd expected".
I would consider these files to be verified, actual MIDI files since they come from the official website of a published lesson book. Any idea how I can open them? I attached one of them here.
