[PD] 8ch diffusion

[Achim Bornhoeft]

Hello Frank,
thank you very much for your patches. I'll have a look at it very soon.
Because of [mtx_mul~] I would like to add iemmatrix to my path list.  
How can I set a new search path for a library when the folder is  
inside the PD package (because I can't open the PD Contents from the  
window that opens.)
Thanks for help.

Achim
