How To Interpret Values Of Parameters Of Midi File Analysis Especially The "data" Field Of "midi.noteonevent"?

I am trying to analyse MIDI files using a toolkit python-midi for python (link to the repo). Basically, my question is about the interpretation of the data I just extracted. Here

Solution 1:

1. The data field of the TrackNameEvent is the same as the text, only without trying to decode it.

2. The note number is is the only thing that matters for MIDI. How you want do label it ("C1", or "kick drum", or "71") is not important, and might be different in different programs.
