The new Perpendicular Compression Mode in Mixbus is a feature you won't find in any other DAW!

Just do what everyone else does and map Ctrl + Shift + Caps Lock + Tab + Tilda + Escape to the much simpler Alt-F4. Whatever you had been doing with your compressor, Alt-F4 will likely be an improvement.

great tip - I find the karate chop very helpful in the loudness war :-)
