I am looking for a tool that can diff/compare Guitar Pro (5) files. Which of these file types should/could I use to compare tablatures? GP5 exports these file types:

  • MIDI
  • ASCII
  • MusicXML
  • GP5

These are probably not so good for comparison, but can be exported from GP5:

  • Wave
  • BMP
  • PDF

What is the best way to diff tablatures?

UPDATE
To make my question a bit clearer: I am looking for a comparison tool which gives me a nice overview of what has changed in the tablature. I already know that the files are different, but I want to know what is the difference between the two files. I am looking in a contextual matter, not in bits and bytes.

ASCII or MusicXML might be good, as they are plain text. I suspect that if they are created by different people though, almost everything will be different.

I'd export both as ascii to start with, then just run

diff file1.txt file2.txt

to compare. If you don't have the standard unix tools available for whatever reason, then I believe dc.exe is available for Windows.

  • Exporting to ASCII forces me to diff every track of the GP separately. So if I have 6 instruments, I need to do 12 manual exports and 6 diffs. Which is far from optimal I think. MusicXML is doable, but it doesn't give me a correct overview of what is happening, because it is a large file with a lot of irrelevant information. Every note is defined by a tag or 8. – Marnix May 8 '11 at 21:18
