Not sure what you mean by "song music window is small". The GUI can be full screen.

Here are three points.

1) Guitar-Pro has been around for decades. Goes back to my early days with BIAB. They have grown and expanded over the years. Which is one reason there is a huge library of song files. And I mean huge! You may have to google "GP songs". In the old days these were all avialable for download. However, times have changed. I don't know how this is being managed today.

2) Currently Version 8 is available. This added Audio tracks for the first time. See attached video which illustrates the "GUI" along with how to operate with the audio track.


3) And in case you think this software is not a fully mature notation tool, this should change you mind



And finally, Yes, that is David who has been my guitar teacher for the past 10 years. grin
