Who is it for?
- It suits people who want to make beats, loops or full tracks on a desktop computer without paying: the download page says downloading and using LMMS is free, and the README names the GPL-2.0 license.
- It suits beginners who like to compose with patterns and a piano roll: the manual's first-song tutorial walks from a preset instrument to a melody, an arrangement, drum patterns and a mixer check.
- It suits users who work with a MIDI keyboard or computer keyboard, SoundFont (SF2), GIG or GUS instruments, or VST instruments, all of which the home page and manual describe.
- It suits people who like to inspect or contribute to the code: the README is hosted on GitHub and welcomes contributions to programming, artwork, testing and demo songs.
