Hi Marc,
nice to hear, that you have a workflow. For the record I noted two
things in the file. (And if there's some spare time, I might further
work on it.)
Thanks for the continuing work on that issue!
1. The durations are tagged by score and stored in an a-list, so you
can first collect durations in multiple scores and display them later
with a score-unique tag.
The tagging works fine, but as soon as I have a layout block in the
\score creating the exact midi file, lilypond prints it :-(
Moving the callback from \layout {} to \midi {} yields to
Programming error: Cannot find key `scoreBACH' in alist, setting to `0'.
So I still have to use my solution with the auxiliary files, which is no
problem at all.

This sounds promising, but IMHO it would be easier to get the engraver
to work somehow on a \score with a \midi { } block only and transferring
the duration to another \score.
Cheers,
Marc

I thought of writing the duration to a external file to be read
from within the markup call in the score to be printed, but did
not follow this route any further yet.
Update: a simple test file shows that this works.
I can
- compute the total duration of a file designed for midi output
only by means of your engraver - write the duration to a file and -
read that string while processing the "print-only" file.
Merging that stuff together with some Makefile should be
straightforward, I hope ;-)
And it has the advantage that some MIDI-related changes do not
appear in the printed score, but the duration will be updated
accordingly.
Cheers,
Marc
