Interesting, let me see..
I have to see if Frescobaldi has an internal representation of durations and
time signatures/bar length, but I guess not. This way the conversion from
parallel back to sequential is a bit tricky since you need to keep track of the
current time signature.
I try to do it as as a standalone Python function so Fresobaldi and other
editors can use it. No promises..
