Hi, I can't figure this one out - did a search and read the specs but still don't know how many tracks I can record at once with an Mbox. I'd like to set up a laptop with an Mbox so I can do remote recording, then bring the tracks back and edit them on my Mix system at home. I want to do be able to record four tracks at once. If I understand correctly, the Mbox has two xlr in's w/preamps, and two 1/4" line ins. Can they all be enabled at the same time? Can the USB channel handle 4 tracks in at once? Thanks for your help, and your patience if this is addressed somewhere already. dave
