LMMS is a free and open-source music editor. If you are a composer, music producer, or recording artist then having a music editor to take your music to the next level is absolutely essential. Unfortunately, the market is flooded with music software that is incredibly expensive. Obviously, these aren’t recommended for anyone who’s just starting out in the industry. This is where LMMS has an advantage. Not only does it come packed with a lot of powerful features, but it is also completely free.
