So if I understand this correctly, the Audiounits protocal is OS level, and Logic is only supporting going forward. Ok. Now, does this also mean that Emagic's own plug-ins and instruments will no longer be confined to use withing Logic? Can DP 3, Cubase, or whatever other sequencers eventually support Audiounits will be able to access Logic's plug's? I'd imagine the XSKey would still be required, but this still holds intersting possibilities. hmmm... Sean G.
