I just posted one: http://footils.org/cms/show/41
it's using dyn~ to create the model, but the basic sound-producing
engine is there, too: Just write the masses' positions into a
[0( mass positions:
| | | | | | | ...
[pack 0 0 0 0 0 0 ...]
Then use "tablename" as source for a wavetable oscillator like
tabplay~, tabread4~ or xgroove~
In my patch, the array "$0-s" is used like that, however the [pack 0
0...] is hidden inside the dyn. corde.pd by Cyrille was posted here
1-2 weeks ago and uses a more direct approach.
You get the masses' positions from [massXX] first outlet by unpacking
the messages coming out of there. It's in the hep patch, but I think
the mass2D help patch has an error: you only [unpack s f f] here, not
[unpack s f f f]
