Lets say im running a MOTU 828 with a PowerBook... now, in this situation, will the quality of the PowerBook's soundcard matter at all? meaning, will it affect the quality of my recording and playback? is it even operating? I ask this because I have the impression that the only task of the computer in this case is to edit and store the data while the MOTU is in charge of the signal converting and determines sound quality. almost as if the interface IS the soundcard. also, the 828 is promoted as a device that runs idealy with a computer, which is another reason. do i have the right idea here? or am i way off? please clarify this for me, this is important for me to understand. thank you.
