I know Cyril's been asking for this for a while and well, the new patch
lets you use the Lips
or the Microsoft Wireless Mics with Rock Band 2
now along with a few other things. You can grab a list of updates from the forum pos
t but another nice little addition is that it adds the handling of chord hammer ons and pull offs from The Beatles: Rock Band
into the game as well.
Now, with the support for a wireless mic, I don't see why you wouldn't pick up the Lips
pack which features two mics over the single wireless mic that Microsoft sells at around the same price.
