My Thoughts:
The simplest way of universalizing this would be to use an audio format for sharing, instead of a Guitar Pro file.
That way, anyone who has audio editing software can Use/Edit the other sound files, regardless of most formats.
Also, for those that don't have audio editing software, obtaining free software (like
Audacity)
allows more people to potentially participate.
Also also, you can simply DO more with audio programs than you can with Guitar Pro.
Personally, I like Guitar Pro and and have used it a lot in the past, But I wouldn't expect many people who aren't
familiar with it to learn how to use it.
Ofganza, if you want to do something strictly Guitar Pro, i'm down with
that, too. I used to use guitar pro for midi writing, then messing with the midi in Fruity loops and Cool Edit Pro.
Fun, if sophomoric, times.
