This would surely be transcription.  Duaine is taking a piece of music
from one medium (presumably sheet music intended for performance on a
piano or keyboard) and literally transcribing the same music, without
any re-arrangement, for another medium, in this case a piano roll.

Adding some bass octaves does not, in my opinion, constitute a new
arrangement; Duane is merely extending something pre-existing in the
arrangement which he is transcribing.
