I realise it's old and probably obsolete, but does the PeRColate library still exist? It's not found by Deken. I can see that there's a GitHub repo for the source that was updated last five years ago.

Alternatively, does anyone know of a library that has any kind of physical model of a metallophone of some sort (e.g. xylophone, marimba, bell, etc.)

Thanks!
