I'm usually on mic for RB2, and noticed there is quite a difference in the vocals for LRB. For one, the indicator arrow is never smooth, it's always jittering (not like the true shaky arrow at least). It is much more picky on pitch, and as usual... there are many talkie sections that don't register sound at all (same for RB2 and some particular downloads).
Anybody else have these issues? I'm looking forward to pulling them into RB2 soon, even if just for the smooth arrow (most the time).
