LMMS aims to be a free alternative to popular (but commercial and closed- source) programs. It is a full-featured music production system that gives you the ability to produce music with your computer by creating cool loops, synthesizing and mixing sounds, arranging samples, having more fun with your MIDI-keyboard and much more. LMMS combines the features of a tracker-/sequencer-program (pattern-/channel-/ sample-/song-/effect-management) and those of powerful synthesizers and samplers in a modern, user-friendly and easy to use graphical user interface. Even though there is a word "Linux" in its name, it supports Linux, Windows, and OS X operating system.
