I dont know if this is win 1809 or the latest cubase 9.5.4 or the combo. Im testing out both today.
When ever I select that I want to use “No bus” on a audio channel in the Vst mixer . It forces to load 1 of my project outputs instead.
I have 26 mono outputs and 16 stereo outputs in the project audio setup. It always select my mono output 4 instead of killing the output. I can turn off the output in the direct routing. But I cant select No bus.
Also using the direct routing.
In non sum mode, The channel only updates info on changes done in the first slot. If I flip output to slot two, the channel dosent update. The audio part works. but it is a mess when you flip from stereo to mono output visa versa.
