In Ableton, there is the “Audio Effect Rack,” and in FL Studio, I believe it is called “Patcher,” which allows you to set up a parallel signal path within a channel/track. This is very useful, for example, for setting up a parallel path with a room reverb without having to open an extra FX send. In addition, the mix of the dry signal and the room reverb can then be processed together in the original channel. In Cubase, you would currently have to open an FX path and then route the original dry track + the return to a new group in order to be able to process the mix of the two tracks together. Unfortunately, this is very cumbersome and confusing. Is such a feature planned for Cubase? That would be really great!
