Cubasis 3 gives me the workflow I’m searching for in a DAW on iOS so I take the time to report those issues. Hope this helps, keep your very nice work going, I love CB3 
Summary/title
Freezing a track will lead to effects sends processing summation
Description
When freezing a track, send effect processing is frozen too, but send effect setting is duplicated on frozen track so send effect processing is summed (or heard two times).
Actual results
Freeze a track with a delay or reverb as send effect (use 100% wet mix and high value send slider settings for better test). The send effect setting is duplicated and enabled on frozen track. As the send effect processing is also frozen, track is actually processed two times by this send effect.
Expected results
This one is not a bug, but very confusing. I fact I discovered it only when freezing an organ dub style track with some delay processing. This can lead to bad mixing when tracks are frozen. IMHO, when freezing a track sends settings should be duplicated but disabled to avoid that. It’s still possible to re-enabling them if needed.
Environment
Cubasis 3.1.1, iPhone 7 Plus, iOS 13.5.1.
