TuxGuitar

Julián Casadesús started TuxGuitar in 2005 to give guitarists a free, cross-platform tab editor when the leading commercial option ran only on Windows, and maintainers guiv42 and helge17 have kept the Java codebase building since taking it over in 2023. That Java foundation is why the interface runs unmodified across platforms, but it is also why the built-in playback engine trails the native sound engines paid rivals ship with.

Why TuxGuitar instead of Guitar Pro

TuxGuitar covers the job most people do with a tab: open a file someone else wrote, read it in tablature and standard notation, mute or solo a track, slow the tempo and print or export the result. It reads and writes Guitar Pro's gp3, gp4, gp5 and gpx formats through a bundled plugin, plus MusicXML, so files created in Guitar Pro round-trip without a paid license. Guitar Pro's edge is the audio: its Realistic Sound Engine renders amp and pickup modeling from recorded samples, while TuxGuitar plays the same score through the bundled Gervill Java synthesizer or an optional Fluidsynth soundfont, both noticeably thinner and, on some Linux setups, reported to lag half a second behind the cursor.

The performance trade shows up at scale. TuxGuitar opens and edits typical multitrack scores quickly on modest hardware, but SourceForge reviewers have flagged specific releases as unstable on larger scores — one called version 1.6.6 "unusable" for repeated crashes. Guitar Pro's engine stays steadier at that size because it targets one file format instead of converting several. TuxGuitar wins on cost and format coverage; Guitar Pro wins on reliable, realistic playback once a project gets big.

What it does well

• Opens and saves Guitar Pro's gp3/gp4/gp5/gpx formats plus MusicXML, so a tab shared by another musician loads without conversion.
• Synchronized tablature and standard notation views update together, helping a player check a fingering against the written note.
• Per-track mute and solo during playback, useful for isolating a lead line while the rest of the arrangement keeps playing.
• Built-in metronome and count-in for practicing a passage in time before playing along.
• PDF export through the bundled iText library, letting a finished tab be printed or emailed without reopening TuxGuitar.

Limitations

• The default Gervill synthesizer sounds thin next to Guitar Pro's sample-based engine, and community reports describe an audible lag between the cursor and the sound on some Linux setups.
