Wanted: open-source, cross-platform music notation

What I'm looking for is an open-source, cross-platform (Linux, Windows, and preferably also MacOS) program for music notation. Preferably with the ability to export to Lilypond (for typesetting), ABC, and MusicXML. Must import and export MIDI files and play via MIDI. Rosegarden would be absolutely ideal, except that it only runs on Linux (for a change).

Canorus looks plausible, but appears to be immature at this point. Definitely worth a try, though, since there are Windows binaries on the download page. It's based on the earlier Noteedit, which is Linux-only again.

Of course, we could always use VMWare and either run Lilypond on Windows, or a pirated version of Concertware on Linux. The latter is ancient, though, and stuck with proprietary formats.

The concert at ConChord

My toastmaster's concert at ConChord, which happened a week ago last Saturday, is finally split up, properly indexed, and uploaded. You can find it here. For field recordings, the sound quality is remarkably good; they were captured on my H2, just in front of the audience. The performances a little less so, but parts of it are, if not awesome, at least served up with win and a modest amount of awesome sauce. I did tear up at the ending of QV, so that says something.
