Chapters:
0:00 PCM 1, 2, and 3

4:39 Square 1, Square 2, PCM 1, 2, and 3
6:12 All Channels
This is an oscilloscope deconstruction of Farewell from Mega Man Battle Network 3.
Notes:
Unlike the previous two ending themes (End Roll and Peace Again), which are composed with a long intro which is not repeated, followed by a short loop, Farewell has no intro and is composed solely of an unusually long loop.
However, the first loop is not identical to the subsequent loops. As far as I can tell, there are a few minor differences.
First, at the beginning of square 1, the first loop has a few notes play on both sides at once, while subsequent loops have them only on the right or left. Again, this only happens with a couple of notes, so the effect is hardly noticeable.
In addition, the timbre of the second instrument played in PCM 1 (can be heard at 0:30 - 0:46 and 5:09 - 5:25) sounds ever so slightly different in the first loop. I believe this is because of a slight tremolo effect which is added in later loops but absent from the first one.
What do you think of this deconstruction? Let me know in the comments.

This song makes me so happy and sad at same time
