When working on compositions in a multi-member band (currently 5 in AnotherDay, each member tends to create their own Guitar Pro files to avoid overwriting the previous versions created by other band members. And
.gp files tend to accumulate for the same song. At which point I start to wonder: "I know there's this riff in one of the versions, but which one ?" or "Are these two files really different or could I just merge them by editing a few notes, or remove one altogether ?"
