Your be either one rme hammerfall + digital mixing desk with adat 
connectors. Otherwise you can use multiple cards but they need to be 
wordclock synced so you tracks stay in sample sync with each other. In 
that case you could use two rme hdsp multifaces, 2 midiman delta1010s 
and there are a couple of other 8 i/o cards with ALSA support.

If you use jack you will have an easy to understand interface for 
routing the i/o's.

  Apparently upon the beginning of the barrage, the donkey broke 
discipline and panicked, toppling the cart. At that point, the rockets 
disconnected from the timer, leaving them strewn around the street. 
Tethered to the now toppled cart, the donkey was unable to escape before 
the arrival of U.S. troops.
