Oh boy, I have had so many questions I love it when as a Newbie I can answer one. This is what I learned from Ray Thigpen re your question. Once you have saved your SEQ file you are ready to merge your mix to a stereo WAV file. Go to the Audio menu and select "Merge Audio and DXi Tracks to Stereo Wave File". I am making an assumption here that you have alread mixed and mastered your track and have the sound you want and have saved it as your master. If that is so you can just launc your CD Burner. I sugest you download and study the Basic Mixing and Mastering with RealBand by Ray Thigpen. He has made the process almost dummy proof.
