OK. I have a track recorded and wish to do a reasonable mastering job using Logic 9. So I go to youtube and 'LYNDA Training video' and the screenshots show a single track waveform which clearly represents a stereo track version of a recorded song. The question is, how do I turn my 20 odd track song into a stereo track to begin compressing, limiting etc. I tried bouncing the track as an 'aiff' file which popped up and played in itunes, but when I tried loading that aiff file into logic, it was 'greyed out' and wouldn't load. Please help me!!!
