In Sonar X1 I had this Master bus and a metronome bus
that were always there in a project but now in Sonar 2015,
I don't see these in my project.
 
I might have changed something around inadvertently.
 
Anyway, is there a way to create this master bus that
all tracks go through?  And that can also have effects
on it?
 
Thank You.

Create a stereo bus, name it "Master," and set the outputs of all the tracks to Master.

Create a stereo bus, name it "Master," and set the outputs of all the tracks to Master.

+ set it as default bus.

If you start a new project and use one of the Sonar project templates, you'll have your Master Bus included (and perhaps other busses and plugins, depending on which template you choose.)

If you use one of the templates to start a project you should have both a master and metronome bus. Also check to be sure the master buses are not hidden.

Do you maybe have "Buses" unchecked in the CV "Strips" dropdown?
