Many small contributions have been integrated into release 6.4, mostly related to the MusicXML importer and MIDI output. They illustrate the widespread adoption of Verovio for these tasks.

Why Verovio?

Verovio is named after a Dutch music engraver, Simone Verovio, who was active in Rome in the late sixteenth century. He was one of the very first to use engraving on copper plates for printing music, a technique that was revealed to be the most suited to music about one century later.
