I know this is going to be a question that should be obvious...but digital audio is not my first field. I am looking for a device that will let me hook up two XLR microphones and record into my powerbook. The catch is that I want the sound from each microphone recorded on its own seperate track. Is that possible with the mbox? If not, what other products [in the same price range do this]...and also, has anyone ever used the Tascam US-122 - it looks to be about the same thing as the Mbox [with different software]...but if anyone knows if this supports the kind of multitrack recording I need, i.d love to save the money. Thanks, Christien.
