What do you mean by "export"? Do you mean you want Logic tracks coming up on your mixer
In which case, yes you can, you just need an audio interface with
as many outputs as your desk has inputs. So if you want for example 16 channels out of
Logic, you'll need an audio interface that has 16 outputs, take those 16 outputs into your
analog desk, then in Logic you just route each track to each output.
