hi , im trying to learn pmpd, ive read in the tutorial that movements of particles can be used for create new sounds... "The movement of one of the masses in the figure 8 membrane is recorded in the pd environment. Sound can be produced using this movement by using the recorded positions as a wave table."
do anybody has an example patch of this???
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 wavetable using:
trigger:
[0( mass positions:
| | | | | | | ...
[pack 0 0 0 0 0 0 ...]
|
[s tablename]
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]
