Guitar Pro is a multitrack editor of guitar and bass tablature and musical scores, possessing a built-in MIDI-editor, a plotter of chords, a player, a metronome and other tools for guitarists and musicians. It has versions for Windows, Mac OS X (Intel processors only), and Linux and is written by the French company Arobas Music.
There have been four popular public major releases of the software: versions 3–6. Guitar Pro was initially designed as a tablature editor, but has since evolved into a full-fledged score writer including support for many musical instruments other than guitar.
Until it reached version 4, the software was only available for Microsoft Windows. Later, Guitar Pro 5 (released November 2005) undertook a year-long porting effort and Guitar Pro 5 for the Mac OS X was released in July 2006. On April 5, 2010, Guitar Pro 6, a completely redesigned version, was released. This version also supports Linux, with Ubuntu being the officially supported distribution.
