Is it possible to split to split mono input channel in two or more channels with different VST plugins and record it on different tracks? I would like to have this possibility shown on this scheme:
Yes it is 
I expected that reply! 
Ha… 
Keep up the good work my man, you’ll get there in the end 
And the way to split channels is…?
You need a Y-split cable adapter.
Thanks!
I can do that using DI box, but I was wondering how to do that digitally, in cubase?
One should be able to do that in DAW, since it’s kind of virtual studio without physical limitation…
You should ask that in the Cubase forum, or maybe you should just think about it a little bit.
Make two mono channels and set the inputs to the same bus.
