[PD] To divide a number in random parts

Until now tim's solution seems best for me, I'll try to build the patch
You know what would be really nice? If it were possible for the computer to
translate the durations into musical rhythms (in lilypond or musicXML for
instance). The user input the total duration, the number of divisions, the
minimum and maximum duration of each sub-section and maybe a tempo and the
computer outputs rhythmic figures. To make things even nicer but a lot
harder, the user could for instance choose between different degrees of
approximations in the rhythmic output so the result would be easier to read
/ less precise or harder to read / more precise.
Here I go again trying to transform Pd into OpenMusic.
And by the way (a little off-topic now): Mathieu, I recently compilated
GridFlow and tried the [note] object you did. Humm! What a nice object.
I still would prefer that the output would be the midi note and the slide to
go chromatically because at least for me is so much easier for the
calculations, but kudos to you.
