I use an ES-9 to send everything to my iPad, where I use AUM to mix it. AUM can also add effects, side chain compression, etc, so I'm finding it very flexible. With it, you can record each track separately. I also send everything to a mix bus, on which I apply a final EQ (removing hiss if necessary, for example), and I record that as well for publication.
