The Logic Off Topic list

Hi All, I need some advice on how to hook up a computer based 
HD recording system that uses a lot of synths (4-5) but few to 
none mics.  That is, I have a bunch of stereo line output devices 
that I need to get into the computer, mix, and monitor.

My current set-up is everything goes into a Mackie 1202 (too 
small for my current # of synths) and through an M-Audio delta 
66 and into a mac G4.

I occasionally use one of the mic preamps on the 1202 to record 
some guitar and vocals but that doesn't happen too often.

What I need is a way to get a lot of stereo inputs mixed and into 
the computer so I can use them all at once.  How do people do 
this w/o using a big mixer?  Is there another way to do this w/o 
using a big mixer?  I don't use half the stuff on the 1202 
(panning/eq/ etc all happens inside the sequencer (logic)) and I 
would like to eliminate the mixer part altogether if possible.

I am probably missing something obvious here.

Thanks,
Dave
