I'm trying to create a posterize effect patch for video (using GEM).  I
found one in the PixelTango object [pt.layerfx] but I can't seem to
figure out how to access the GEM subpatch that powers it.  Can anybody
tell me how to access the posterize subpatch in [pt.layerfx]?<br><br>Alternately,
can anybody give me advice on how to create a posterize patch from the
ground up?&nbsp; Basically I&#39;m trying to reduce the number of colors in the
video image.&nbsp; I don&#39;t even know where to begin so anything will help.<br><br>Thanks!
