Thank you. I understood where I was wrong..there are two software versions, one is for hardware and the other is the software-only version (and it must be authorized, too bad..does anyone have the authorized disk image??). the hardware version works.. i haven't managed to route the audio outputs directly in protools yet.. the manual says it's possible but it refers me to another guide where, however, it doesn't mention how to do it. has anyone succeeded? did he see the audio outputs directly in protools? ( very handy to add efx ..
