In the past i have always built my surround mixes from stereo sources. However, my new camera records 5.1 and i am trying to find a way to BG all channels at once without having to adjust a volume envelope on each of 4 tracks. Assigning all 4 tracks to a buss downmixes them to stereo. Is there any way i can group together 4 surround tracks and rubber band the level?
[edit] ganging the 4 tracks of the surround audio together and using automation to adjust all 4 tracks at once is my workaround for the moment.
