How to describe a piece measure by measure?

[Tobias Kunze]

it seems to me as if you could port your def-* forms almost trivially
to cm, from where you can write a cmn score file.  You'll want to
add some cmn objects in the stella structure, if you don't want cm
to guess at the barlines and meters, though.

writing a lisp function to convert from horizontal to vertical representation
doesn't strike me as trivial, however :)  since you'll have to time-sort
events on the fly.
