There's a new JFugue-related project on Google Code: jfugue-scala
Earlier this year, Joshua Gooding (aka skavookie) started to creatie a Scala-based parser for JFugue's MusicStrings. There has been a lot of good work on this side-project, but there's also a fair amount more to do. The work had been done under the main JFugue project, but given the project's infancy, I'd like to move it to its own project for now. When the Scala-based parser is more solid, I'll be happy to promote it to the main JFugue project.
In the meantime, if you're interested in JFugue and Scala, I invite you to check out and contribute to this project!
