I've been looking into some recording stuff and these keep poping up. Are the different from a DAT,? and if so, how? I was looking through Musicans freind or AMS or something and saw they were selling an Alessis Mixer and ADAT machine as a recording package. I Allready have a mixer so I was thinking I could get An ADAT and use it with the mixer I have (mackie CFX-12). Would this work for multi track recording??
