Big Mixer Window missing

Where is it?

Looking at the ntack screen shots on the home page, the second view is of the Main Mixer. Where can I find that?

The view tab along top of the program is where you’ll options for viewing mixers, “toggle all mixers” for example. You need to create at least one track or all you’ll see is the master fader, so create 5 or 6 tracks and then you look at it.
