You can dump midi into audio without bouncing it and then importing it again. Do you just bus it to another track and then record it, or is there another way?
You HAVE to do that if you want to take the track to another studio to get it mixed. If you don't, then you're going to pay for an ass load of time for them to find the sounds you want to assign to the midi notes, because midi sounds don't travel with the file.
