The GTP Preview plugin allows Obsidian users to preview and interact with Guitar Pro files directly within their vault. Supporting file formats such as `gtp`, `gp`, `gp5`, and `gpx`, this plugin utilizes AlphaTab to render music notation. Users can view and switch between multiple tracks in a file and even download MIDI versions of their compositions. It provides a seamless way to incorporate and work with Guitar Pro content within Obsidian.
