LMMS

LMMS aims to be a free alternative to popular (but commercial and closed- source) programs like FruityLoops, Cubase and Logic giving you the ability of producing 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 and those of powerful synthesizers and samplers in a modern, user-friendly and easy to use graphical user-interface.

Using LMMS you can produce electronic music with your computer, so you don't have to buy expensive hardware for having great sounds and making cool music. Of course no software can replace real hardware-synths, but you'll have still much fun with LMMS and especially users being new to music-production at all will learn things in a really easy way! LMMS provides software-synths and other plugins, cool presets for them and also some essential samples.
