but I'm missing some step. When the "track view" press "Waves" tells me "No Track to Open Waves Display". I do not understand then how to proceed.
The step you are missing is that the wave-view window is not showing you what you want to see.
Check these things
Make sure your Vocal Track is the current track
At the top of the Track screen is a small window the tells you what track will be pictured (displayed) in the view window. Make sure that number is the number of the track on which you have your vocal.
If the wav is not already displayed then cursor to the button that turns the wav display on/off and turn it on. Now you are looking at the wav of your vocal.
Next, if the wav is not very prominent, (or conversely too big) explore the buttons in the wav display window. They change amplitude, size (length shown), cursor position, track # of display. there is a listen button too.
You will use these controls to precisely locate the beginning and ending points of the sections you want to attenuate (play at lower volume). Drop markers at these points, or work directly back and forth with the EDIT screen, the purpose of which will be to MOVE a small section to another track. When done, this section is not on the original track any more because you used MOVE, not COPY.
Set the volume of this "destination" track a few dB lower (I'd use the VIEW button >FADER screen to do this precisely and also I'd save it to a scene)
Make sure the new track is "on" in the MONITOR windo, so it will be part of the mix
Now play back the mix. and those small sections should play back with less volume and no glitches, as long as you were careful to always accurately observe and set the proper starting point on the destination track AND if any EQ and DYN and EFF settings are identical for the original and the new track. Save all this stuff to the scene as you dial it in.
You will be able to do all these steps quite efficiently with some practice.
