I go to open files. at the bottom there are lines. top is file name. the bottom is files of type.right now its set to open all files bb files. mgu,sgu, wave, mp3, mp4 and so on. I used to be able to set to just do mgu and sgu and would hide the rest until I changed it. I for recording purposes have made wave files for separate tracks to export. I can go back and bring the song into a recording file and then make wave files if we can't come up with a plan. thanks for your help John
