First... can you change a active timeline from stereo to mulititrack 16 channels for instance without creating a new sequence and pasting old sequence into new one.
Also, watch this video...
16 channels of audio... great... try to match sequence settings it changes from 16 channels to stereo. Um... what's happening there???? How do we fix that?
I realize for the most part. @adobePremiere keeps sending me here to post.
I would do it on the prerelease forums but they closed now. Many of the twitter guys I know where in the prerelease program so it's better feedback there.
Jim, this is the best place for Mike to post.
This is where the Premiere Pro engineers, testers, and product managers will see questions. It's extremely cumbersome to try to forward a tweet to the relevant expert, and it's even worse to try to troubleshoot and give answers longer than 140 characters (with screenshots) over Twitter.
That said, I'll get someone more familiar with the new audio features to have a look.
I actually agree that the 'Match Sequence Settings' checkbox should also apply to the number of output audio channels, and have noted this as a feature request. There isn't really a particularly workaround to this right now and the way you're doing it is the way I'd recommend.
Sorry, and thanks for the feedback..
