Precisely. I chose
c cs d eb e f fs g af a bf b c
for C major, and changed the cs to df for C minor. This is the best
guess you can produce for individual MIDI notes.
More sophisticated analysis would require knowledge of all
simultaneous pitches from each voice, along with previous and
subsequent pitches in each voice, many of which would not have been
entered yet. E.g. a perfect system would spell an ascending chromatic
scale in sharps and a descending chromatic scale in flats.
Unfortunately, I think this would require the routine to predict the
future.
