Hi, Cyrille,
The pmpd* object initial link length is the creation length. this is diferent from the link object where length is manually specified. The good things about this is that the created structure is mostly stable after it's creation. The bad thing is that link length can be different of what you want. in your example, all masses are in position 1, except the fixed mass (0). so the link from 0 to 1 and 0 to 20 have a length of 1. This cause unexpected problem in boundaries.
If you set masses position to 0, or send a message to set link length to 0, everything should be fine.
I see, it works now with mass position = 0. Then there is still one thing I don't understand, all the masses are actually fixed, and created with "mass sound 1 ...". But they still move to make sound?
I'll try to do a visualisation of the data, maybe I'll understand it better.
your patch made me realize a bug with negative length links in 1d simulation. I just fixed it in svn.
cheers c
One thing, there is still a high resonance, just like in the original [pmpd~] example. I imagine this is a limit of the synthesis method?
Best,
Joao
