Rosegarden

                                                                                                                       Rosegarden is a free software digital audio workstation program developed for Linux with ALSA and QT4. It acts as an audio and MIDI sequencer, scorewriter and musical composition and editing tool. It is intended to be a free alternative to such applications as Cubase.Software synthesizer is available as a plugin, and it is possible to use external MIDI synthesizer, hardware or software (such as FluidSynth or TiMidity 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.Rosegarden was developed up through 1.0 by Chris Cannam, Richard Bown and Guillaume Laurent. Since then, each release has been developed by a different mix of core and contributing project members, including, but not limited to D. Michael McIntyre, Pedro Lopez-Cabanillas, and Heikki Junes. Bown has retired from the project, while Laurent has left to pursue his interest in porting to Mac OS X via Cocoa in an as yet unnamed spinoff project. A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification.There is no standard for defining the term, and some difference of opinion is possible as to the degree to which a given OS is "Unix-like".The term can include free and open source operating systems inspired by Bell Labs’ Unix or designed to emulate its features, commercial and proprietary work-alikes, and even versions based on the licensed UNIX source code (which may be sufficiently "Unix-like" to pass certification and bear the "UNIX" trademark).
