We are working on a short documentary and are having playback issues within the sequences that have multiple channels of audio. There's an interview portion where there are 7 channels and whenever I skip around in the sequence, I get the spinning beach ball. I feel like I am choking out Premiere. Is there a certain way I need to have my sequence set up? I have it set to "Multichannel" and then have 7 channels of audio. Then I have 7 audio tracks, set to Standard. I am running Premiere CC 2014 8.1 on a 2010 MacPro.
