Hi there I have been working with pro tools and biab from the begining. I just get the biab song the way I want reaktracks and all. Then I rendered to seperate tracks, which are wave files I guess? Then go the protools and go to import tracks. You can lisen to them before adding them. When you have what you want prees done and it generates tracks for each. If you decide later you want anouther reaktrack go back to biab and use generate it and then import it. You will have to name the tracks wants you get them in protools. I have found stuff that was turned low in biab that i brought up. Sometimes I use the realtracks along with a lead I play more like what the big boys do have fun
