I have a ultralite MKII
it rocks!
solid!
It only has 2 mic pre's
so you would need 4 (or 2 stereo) more mic pres for what you are suggesting
it will record in the supplied AudioDesk software
6 separate channels and you can post mix
also you get a sweet little app called Cue mix you can make separate mixes to separate pairs of outs for multiple stereo mixes- or a 6 channel surround sound mix
check out the motu forum on the MOTU site
it is for both multi track and can be used w/o a computer as a standalone mixer- but I think you would then be better off with an allen & heath mixer or the like..
you can mix with e the controls on the unit, however it is not as handy as when it's connected firewire to a computer- Mac
if you have a Mac MOTU is the way to go - unless you can get a Metric Halo
but if you need more mic pres you might look at the MOTU traveler- with 4 pres
or ditch the lappy all together for the cost and go with the new 6 channel tascam recorder - DR-680
