Hi David! I am a braziliaan musician/singer/engineer. I use Pro Tools TDM v 5.1.1, with 2 adat bridges light piped to an 02R at 44.1k/24 bits most of the time. I intend to authorize AMP FARM and Echo farm, as you know, both ask for floppy authorization. I use a G4 800, with 512MB RAM, 140GB HD with a Mix system inside ( d24 + mix farm + DSP Farm II). Which USB drives have you or any other friends being using with success? I have heard rumours of drives that do not recognize or damga authorizations and so... Also, which versions of these plugins are compatible with mix systems? sorry I am asking you stuff that in fact belongs to the DUC.. Nice 2003 !!
