For all the dissing of behringer I am always amazed at often I find their products being used...
I have several of the midi devices that function quite well...that being said both Mackie and Behringer should stay out of your audio signal path where it matters...control info is small and non-intrusive...but let those guys mess with the A/D conversion and you WILL regret it...
(Although there is a mod to bypass the preamps in the behringer octopre that allows a fairly decent conversion...its the stinking preamp channels these guys use that is pure harshness)
I have the same feeling about focusrite...wet blanket comes to mind...
