Freezing a track (audio or midi) in 1.8.1 unmutes any previously muted tracks. This is annoying when the project has over 60 tracks! Tried hard reboot, all the usual stuff. Setup is iPad Air 64mb, iOS 7.1.2, UR44 interface. Any ideas appreciated, thanks 
We have the issue reproducible and work on a fix.
The issue has been fixed with the latest Cubasis 1.8.2 update (available on iTunes).
