GH compatibility

[Cobracon420]

I already have GH:WT. Will any of my PS3 instruments work with RB2?

All instruments will work with RB2.

I understand that GHWT drums and guitars are supposed to play with the Rock Band 2 game and mine do BUT only when played individually - I can not play in band mode with both my drums and guitar together. This is due to the games lack of indiviual calibration on the instruments. Any calibration settings you do count for both instruments and in my case in guitar calibration settins are Audio -20 and Video 25 while the drums need a calibration setting of Audio 102 and Video 59.
This basically makes the game unplayable to me since I like to play with friends on both the guitar and drums.
Just a word of warning for those that think GHWT and Rock Band 2 play nice together :(
