I'm considering getting either a MP or LE set up. I need to record 4 tracks at a time. I know that the MBox2 is technically capable of this (via the dig. inputs) but has anyone here successfully done this? I'm a bit concerned about 4 tracks via USB. I would prefer to go LE as I would get the Ignition Pack, but don't really want to spend $1,200 to record 4 tracks. Any advice is appreciated. I've enjoyed reading these forums, you guys are all very helpful. Thanks!
