Hello :
With a more than decent mixer you´ll definetly hear a difference in 
your mixes. With your mackie I don´t know... Try this : Do a pretty 
good mix internally and bounce it. Then without changing any level 
use separate outputs and with your mixer faders at O ( unity gain ) 
record the resulting mix .  put both on separate outputs, match 
levels and hear them... 
With my soudcraft 1600 I was able to hear the difference even @ 16bit 
with an AW8 . with the Multiface is even bigger. IMHO of course :-)
kind regards
