How to change loudness adjustments professionally?

I’m sure some basic youtube videos will help you. So far from what I can count on this thread you have changed to ask about three completely different things:

  1. How to control the automation of several different tracks using a midi controller sending a single CC value. Answered
  2. How to automate the master volume output. Answered.
  3. Now…you just asked about sending five instrument tracks to a single group track. Yes-this is possible and very simple. I recommend Googling “Cubase Group Routing” to get an understanding of how routing is done and changed within Cubase. The first video that pops up for me is 4 minutes long and you don’t need to wait for a DVD in the mail.
