LMMS – Linux Multimedia Music Studio

Linux has a bunch of wonderful things, but now there’s LMMS! This was built to take on commercial programs such as FruityLoops, Cubase and Logic. WIth this, you can synthesize and mix samples as well rearrange samples.

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.

Pretty useful for those musicians that are looking for something they can work with on a limited budget. Open-source helping artists? You betcha.
