v1.3

For what is for, this is the best stage this snippet has been. 2 volta ritornellos will not print any number; 1 volta will just print the music expression; 3 or more will do the trick as described in the README.

v1.2

If the number of voltas is 1, then it will only print the music (without any repetition, bar lines or similar things). If 2 it will only print the repeat and second volta indication (for unfolded scores). If 3 it will print every functionality described in the readme.

The example uses three instruments with different musical expressions and time signatures (using \enablePolymeter).

v1.1

Updated version of snippet. Better code (less back-and-forth between Scheme and Lilypond code) and add function tailored to specific needs.

v1.0

Original release.
