I was using my old Mackie 1604 (from the ADAT days)until it died.

Obviously it wouldn't work as a control surface, but it did allow me to mic things in stereo, which I couldn't do with 11R's one mic input. I also had grown accustomed to the mic preamps over several years.

I haven't fixed or replaced it, and the 11R's sole mic input has been suitable thus far.

I just got an enormous catalog from Musician's Friend (obviously imitating Sweetwater's model) and there are Presonus mixers that also act as interfaces, coming out. They aren't even on either retailer's web site yet.

They look nice, and affordable, so I will definitely be checking them out.
