Description:

KGuitar is basically a guitar tabulature editor for K Desktop
Environment. It's much more than just a tab editor. It's features are:

* free GPLed K Desktop Environment GUI
* Powerful and convenient tabulature editing, including many effects
and classical note score editing for classic instrument players;
* Full and very customizable MIDI to tabulature import and export;
* Support of extra data formats, such as ASCII tabulatures or popular
programs' format, such as Guitar Pro's or TablEdit;
* Chord fingering construction tools - chord finder & chord analyzer;
* Highly customizable to suit a lot of possible instruments (not only
6-stringed guitars, and even not only guitars), including drum tracks,
lyrics and other MIDI events.

Well, right now KGuitar is in very alpha state and doesn't support
everything stated. However, it already features a nice tabulature
editor, though not ultimately powerful, loading/saving its own format (kg
files) and all the chord construction tools.
