Well all DAW's do that. The great advantage is that the edits are non-destructive. The
problems with logic in this regard are more to do with the complicated way in which it
allows you to handle all these files, place, edit and generally work with them in the
'main' window. Equally it has convoluted way of assigning a sort of function to each track
which is designed to be flexible but just ends up being counter intuitive. The main areas
that an engineer needs when tracking and mixing bands are things like grouping,
automation, clarity and simplicity of use etc. In all these areas logic falls short of PT.
I'm not saying that you cant use it. You certainly can but there's a reason why most
studios use pro tools despite all the problems with it...like the cost, the sub par
converters (pre 192), the closed nature of the system, having to give cash to digidesign,
the appalling midi etc.
It's all about what you need the software to do for
