As of v25, Finale now includes all the extra features from the Dolet plug-in directly from the File menu. There is no longer a need for a plug-in to get the full MusicXML functionality, including batch import and export.
Dolet was a famous French translator of the 16th-century. Our Dolet software is also a translator, but this time between more than 230 music programs that previously could only talk to each other using MIDI files. The name is pronounced “doe-lay”, rhyming with Chevrolet.
