ExpressFX Distortion XFXl

The ExpressFX version of Distortion does not have a graph to customize the effect or a Low pass start freq. filter. 

The Dither plug-in smooths the sharp noise that sometimes results from such a conversion by adding a random hiss to the down conversion artifacts and then changing the frequency of this noise so that it can no longer be heard—or is at least less noticeable to human perception. This comes at a minor price of adding a background hiss, but it allows more of the original low-level 

Dithering should be done on individual tracks if only some tracks will be down converted, bnt it is more typically nsed on the entire project as the very last plug-in, especially when down converting for the Internet. You should definitely avoid using Dither twice, both at the track and the project level.
