somewhere? I could make a patch that would do the same thing, but it would be so much more elegant if you could do riemann sums with an object ...

Hello,
riemanns sums are pretty interesting, I've found an article co-written by M Puckette that is treating the subject:
http://www.crca.ucsd.edu/~syadegar/Publications/YadegariDiss.ps
an html version is temporarily here:
http://megalego.free.fr/pd/rieman-music.htm

did you try [expr] for making something elegant?

thank you for this interesting link. yadegari's dissertation is at UCSD, one of the places that i'm interested in applying to grad school at. i couldn't find anything about (bernard) riemann sums in the essay, only the work of philosopher hugo riemann, but yadegari's documentation on the [expr] argument - which are part of the helpfiles of pd - have been quite helpful.
