There is at IRCAM a pd implementation of modal synthesis, called modalys.

Modal synthesis is different from oscillators or karplus strong, in that it takes account for frequencies AND space data of vibrating structures (modal shapes), making it though possible to synthesize transient sounds and articulations in time domain which are difficult if not impossible to modelize in frequency domain. modalys is a pd library, works in real time and is a (very) simplified version of a lisp / C++ software which was developed in 80s, the latter making sounds more real than natural sounds.
