Submix concept

You need to use sub mixes to organize and simplify the mixing process, and to solve the CPU cuts problems while using a lot's of plugins and effects with out the need to increase your puffer size too much..

With the submix I can insert an effect or set the volume to a multiple tracks or similar set of tracks for example keys or drums at once. 

We will create the bus and name it with a name related to the group of tracks that we want to insert a specific collection of effects or plugins on it.

The bus receives the out puts of my collection of tracks...

 I will stand on each track and send its out put to my bus, and then I will create a single aux track that receives that bus as an input and then I can repeat that process on other instruments.    

I don't have to make all of those steps with my DAW which is Fl studio..  it have a ready collection of buses connected to the mixer and all I have to do is send my audio tracks outputs to the insert that I choose audio tracks in Fl studio calls inserts ..

In Fl studio the mixer audio tracks can work as a regular audio track or as an aux file at the same time and the bus process isn't separate from the audio track which make the mixing much faster.
