Audio is distorting when I play the sequence.

Give us your system and software specs. What computer, version OS, i/o card or device, how you’re monitoring audio and video, drive setup & speed, version FCP, etc.

How are you monitoring your audio? Do you have a mixer?

Oh yeah. I have a Alesis Multimix 8, It takes the feed from the multi-bridge. And runs to KRK rokit5 speakers.

I’m wondering if there might be a ref problem between the Multi Bridge Pro and the mixer. Are you using digital audio connections(aes or spdif) or analog. I’m not familiar with the details of that mixer. Does it need a ref signal or word clock. If the audio isn’t synced properly that could be a reason. You might try disconnecting the mixer and running the output of the Multi Bridge directly to the speakers. Just be sure to lower the gain so you’re not combing speaker parts from your hair.

You should do an Audio Mixdown if you haven’t: Sequence Menu > Render Only > Mixdown. A while back I had some weird audio play issues so I trashed prefs, repaired permissions and ran Disk Warrior. I haven’t had an audio wierdness since.

Thanks for your help John. I’ll give that a try.
