Rosegarden is a MIDI and audio sequencer and musical notation editor whose purpose is to serve as the sequencer of choice for users who prefer to work with music notation. Rosegarden allows you to record, arrange, and compose music, in the shape of traditional score or MIDI data, or of audio files either imported or recorded from a microphone, guitar or whatever audio source you care to specify. You can use Rosegarden to write, edit, and organise music to create a composition, which you can then synthesise, add effects to, and mix down for burning to CD or distribution on the web. Rosegarden also contains well-rounded notation editing support for high quality printed output via LilyPond.
