Wrong octave for MIDI files exported from Ableton

[mclean909]

Hi

I'm exporting a midi file from Ableton, right click -> export midi clip:

When I upload it to https://tonejs.github.io/Midi/

I get C4 instead of C3:

        }
      ]
    }
  ]
}

I uploaded the .midi file here : https://filebin.net/7bh8kh0jz32fdgfx

I'm I missing something or doing something wrong, or is that a bug ?

Thank you
