It seems that UAD only released the mode "release all UAD DSP resources on AU bypass" for DAWS which use AU plugins. I don't know if Cubase uses AU extensions, I think It only uses VST plugins. So with that, it seems that I cannot have this very good mode running on Cubase. Does anyone has a solution about that ?
Here are screenshots with a Manley VoxBox tested on Ableton Live (who uses AU extensions) and Cubase 9 pro (VST extensions).
You see that Ableton accepts the mode "release DSP" when it's bypassed
And here on Cubase you see that it doesn't accepts the "release" mode when it's bypassed
If there is no solution, I have 3 words to say : What a shame !
We would have to bounce/render in place or freeze a lot more than usual
