So I am using a Mackie 1220i hooked up to my PC via firewire to ableton live. My question in brief is how do I mutlitrack? Here is more details; When I select my audio input devices in ableton I see 8 mackie drivers: Mackie CH 1-2, 3-4 and so on. The Mackie CH 13-14 are Aux sends and 15-16 are master. Ableton only lets me choose 1 driver at a time. I can record everything from the board with proper use of the AUX sends by selecting the mackie 13-14 audio input in ableton. I want to have each channel on the mackie go to an individual track in ableton.Ableton doesn't appear to allow to select multiply input devices. Any ideas?
