When I move exponential fade to my audio clip, everything looks good on the Audio clip ( Exponential Fade appears on clip and Effects Controls panel looks good. When I play the clip it does not fade. Constant Gain & Constant Power do not seem to work. I tried the cross fade on audio from my camcorder5.1 and ITunes music. Today the Exponential Fade worked one time everything looked the same as before. I deleted the cross fade and tried again and could not get it to work. I've tried the crossfade Audio a hundred times and it only worked one time. Any Suggestions?
