I checked a forum too, but it's not HD.
It's an M-Powered with some unlocked functions like 128 tracks instead of 64, and something else.
I friend of mine tested the HD and it has the HD icon, the HD word in the menu, etc...but it's M-Powered, because there isn't the HD mixer, there is no I button.
Someone answer me that you can use the HD unlocked only with HD hardware......but it's a ridicolous thing because.....why should I use a cracked HD if I already have all the legit hardware?
To me the only usefull things to unlock should be the track numbers and the possibility to use PT without the M-Audio interface.
