I’ve been recording songs to my MD8 where I use 6 – 8 tracks per song. I would like to get individual tracks off the MD8 and onto my Mac. I do not want to transfer the tracks for each song one at a time and would rather transfer all 8 tracks per song simultaneously so they’re in sync. What software should I use to record 8 individual tracks simultaneously onto Mac? What firewire audio interface should I get that will have 8 inputs that will work with the MD8's RCA outputs? TIA.
