The standard equalizer in the channel strip gives visual feedback. Just select an audio track and click on "Equalizers" in the inspector to get e small visual presentation. To get a bigger presentation, click on the "e" in the inspector and the channel settings window opens. There you can select the "Equalizer" tab to bring up a more detailed view.
Wow, that's a long way to go to get the window to open. I was working on the equalizer in the mix window. I would have expected some way to open the big window from there. This stuff feels like you need a "secret handshake" for so many things that ought to be simple. Last night, I enabled the Control Room, which was easy. There was a big button in the middle of the Control Room display. Later I was afraid this had created to redundant pathing so I wanted to simple disable the control room. I literally searched for over an hour, including going through many articles in the Cubase documentation before i finally figured out you have to press F4 to set another window to pop up -- which doesn't match any of the documentation I saw. On the pop-up window, there is a button to turn off the Control Room.
It seems really twisted to me that such a button would not actually be on the Control Room panel itself.
In the end, the CR was not my problem anyway. That ended up being a different issue outside of Cubase.
