Your discription confuses me as it sounds like your adding a buss, and on that buss adding a effects send??
What's normal is to make a new buss, name it reverb and put the reverb plug in in the buss effects bin.
Now you add that send to your vocal track
And make sure the send to the reverb buss is not pre fader.. use Post. Pre fader will result in you still hearing the reverb with the track fader down.
