I tried to plead my case after The Beatles came out:
But here we are again with a terrible vocal control scheme on Green Day Rock Band for the Harmony vocals. I repeat, having to pause the game to "lower original vocals" is terrible! It completely breaks up the flow of the game while playing a set list or in a group of friends. It also does not allow the freedom of creating a comfortable mix of mic volume and game vocals which so many of our regular players ask for. It has been halfway fixed with the added option of the game mic volume changed on the fly with the "A" button (Xbox 360). I would really like to see the game vocal adjustment mapped to a button also (there are still several left to choose from), to be adjusted on the fly rather than have to pause the game to fix it.
As I said in my original complaint when the Beatles was released... Either keep the vocal and mic adjustments with the same methods as RB1 & RB2 or omite harmonies altogether for RB3 if for some reason it is physicaly impossible (although, I can't see why it couldn't be done). Thanks
