I use an Alexis 6FX and I carry the mixer and my Digitech Vocalist EX workstation harmonizer in a laptop bag ... the section of the bag I use for this has a foam divider right in the center and velcro straps on each side which is great for holding the two units in place ...

PS ... the power supplies for both units go in another bag with whatever cables I need ...
Not NEARLY as concise/compact as Gary's set up, but it works for me ...
