Just started using GEM and PD, and while I am exploring GEM, it seems to me that certain objects for pixel manipulation that are listed as existing (pix_convolve, pix_motionblur, ...) are missing in my setup (the terminal window puts up a error message, and the object itself has no connectors), while other objects work fine (pix_kaleidoscope, pix_aging,...). I am sure that the answer is trivial, but for the while being, I'm rather stuck..
thanks - michael
