the newsletter also linked to the Audiobus forum with a lot more discussion on the matter:Hi folks,
We're on the cusp of iOS 7, and we're here to urge caution: If you rely on music apps, please don't update yet.
iOS 7 audio is not ready. There are a wide variety of bugs that are causing performance problems, crashes and other problems in a large number of music apps.
This may change in the future, but until we see a few point releases for the OS, we strongly urge you to stick with iOS 6.
Cheers,
The Audiobus Team
