LMMS  is  a  free  cross-platform  alternative to commercial programs like FL Studio®, which allow you to
       produce music with your computer. This includes the creation of melodies and  beats,  the  synthesis  and
       mixing  of  sounds, and arranging of samples. You can have fun with your MIDI-keyboard and much more; all
       in a user-friendly and modern interface.

       LMMS features components such as a Song Editor, a Beat+Bassline Editor, a Piano Roll, an FX Mixer as well
       as many powerful instruments and effects.
