Guitar tablature file created by Guitar Pro 6, a music composition program for fretted instruments; saved in a proprietary format and contains musical scores and compositions for bass, guitar, banjo, and drums; can be played in the software, which uses the Guitar Pro engine to simulate the instruments.
The audio in GPX files can be exported to several different file formats, including .GP5 (Guitar Pro 5), .MIDI, and .WAV. The scores can be exported to .PNG, MusicXML, and .PDF formats.
NOTE: GPX files do not contain waveform audio data. Instead, they contain instruments and musical notes that can be simulated as music in the software.
