Here's what we're considering: A mixing studio running Logic Pro 8 on a Mac Pro Quad 4. 2 Aurora 16's. All channels will be running into a 32 channel Toft board for mixing. (we regularly run 30+ channels.) The question is, what would you recommend as an interface card to enable us to run maybe 30 channels out D/A and 2 channels back in A/D? Or is it even a possibility to run D/A and A/D at the same time?
