Rosegarden is a free software digital audio workstation program developed for Linux with ALSA and KDE. It acts as an audio and MIDI sequencer, scorewriter and musical composition and editing tool. It is intended to be a free replacement for such applications as Cubase.

Rosegarden is a well-rounded audio and MIDI sequencer, score editor, and general-purpose music composition and editing environment.

Rosegarden is an easy-to-learn, attractive application that runs on Linux, ideal for composers, musicians, music students, and small studio or home recording environments.

Rosegarden does not provide a built-in software synthesizer, so it requires a hardware MIDI synthesizer, a soft synthesizer such as FluidSynth or TiMidity++, or a synthesizer plugin in order to make any sound from MIDI compositions. Recent versions of Rosegarden support the DSSI software synthesizer plugin interface, and can use some Windows VST plugins through an adapter.
