Thanks for the suggestion. It probably is, but I'll have to make some 
drastical changes to the overall architecture of the patch which at the 
moment is using multiple [pix_texture] objects.

If you were obliged to keep using multiple [pix_teture]s, is there a way 
to "map" the textures "generated" by [pix_texture] objects to the ones 
used in the shader program? I mean based on the texture id's coming out 
from the right outlet of [pix_texture]?

How do I tell the shader "your sampler2D variable MyTex is texture 160" 
where 160 is the id coming out of a [pix_texture] object?
