Hello,
Thanks to all the help provide by Benjamin Wesch, pmpd (Physical Modelling for Pure Data) version 0.13 is ready.
pmpd aim to provide physical modelling (mass/spring system) simulation to control data in natural ways. Audio synthesis is also possible, now in 2d or 3d thanks to the new objects : pmpd2d~ and pmpd3d~.
It's on deken.
Cheers Cyrille
