I'm a recent Line 6 user and I'm not familiar with Line 6 Edit. However, I use Gearbox as the GUI/editor for the X3 - it's a standalone computer application that provides a much better interface for editing Tones and patches in the X3 than using the X3's controls itself. If that's what you're looking for try Gearbox - again available to registered X3 users via Monkey.
