Well, we did say there will be news on big content production software published, didn’t we? New versions of Rosegarden, a MIDI sequencer and score editor, and MuseScore, simply a score editor were released one after another over last several days.
For Rosegarden this is mostly maintenance release with bugfixes that however features one big change: a much saner way to handle tied notes in the pianoroll editor. Such notes now have a subtle pattern fill and are treated as one whole thing. Additionally banks for Kurzweil PC3 and 2500RS, Kawai CA9 MT1 and MT2, as well as Roland SonicCell were added. Rosegarden' primary target platfroms are Linux and UNIXes.
For MuseScore this is the first formally stable release after over 8 years of work. Originally MuseScore was an internal score editor in MIDI sequencer called MusE. It was decided in 2002 to make it a standalone project, and over years MuseScore has become primary project for Werner Schweer — its principal developer.
