The D888 records each track as a WAV file, which can easily be imported into any computer-based recording system, (via high speed USB 2.0).
This is part of its main appeal - it is a great mobile front-end capture recorder for using with a Protools or other system.
As a Home-Studio-in-a-box, it lacks much of the editing, automation and effect of other Korg recorders, and there is no internal CD-Burner.
But as a live recorder it really is nice because it has 8 pre-fader outputs, which means you can use the D888 as your recorder AND mic splitter, to send the mic inputs on a long to a house sound system without screwing with the house mix.
