We're currently organising our staff xmas do, and we were thinking about using Rock Band 3, as I have the previous games, microphones etc.
Since I have a USB Mic and a couple of Wireless ones, I was wondering if you could play Rock Band on No Fail and just blast out songs karaoke-style or whether you'd need to set the players up with Harmonies, and have them work different vocal tracks, etc.
IE can they just straight sing as a solo-player would in RB3 or would they need to harmonise?
