EDIT: I think i Found out what is the 2 and 3 columm
2: what CC or MIDI note is with 15 algorism ( like 0 1 2 3 4 5 6 7 8 9 0A 0B 0C 0D 0D 0E ) But WHYY?
3: Value 2: of CC or MIDI note is with 15 algorism ( like 0 1 2 3 4 5 6 7 8 9 0A 0B 0C 0D 0D 0E ) But WHYYYYYYYY?

It is the data (in hexadecimal representation) from the MIDI messages

The first column is the MIDI message type and MIDI channel index:
for x'90' the first character is the message type, a Note On in this case - starting the note (generally)
for x'90' the second character is the MIDI channel index, MIDI channel 1 in this case, ranging from x'0' to x'F' (channels 01 to 16).

The next column is the note number, e.g x'2B' = 2 * 16 +11 = 43, ranging from x'00' to x'7f') (0 to 127)
The next column is the note velocity, e.g x'1D' = 1 * 16 +13 = 29, ranging from x'00' to x'7f') (0 to 127)

Note Offs can be represented in two ways:
-- with a message type of 8, e.g. x'80' in the first column,
-- as a Note On with a velocity of 0.

So those three columns are the raw data taken from the MIDI message, presenting them in hexadecimal format is just a compact view; the rest of the line is the interpretation of that data into a more understandable form.

You might try these:
https://www.midi.org/specifications-...f-midi-message
https://www.midi.org/specifications-...s-data-bytes-2

But their values are represented in binary, not hexadecimal.

And https://en.wikipedia.org/wiki/MIDI
