LMMS (short for Linux MultiMedia Studio, AKA: Let's Make Music Studio) is a free, open-source and cross-platform digital audio workstation (DAW) program for Windows, Mac and Linux platforms, considered to be one of the best alternatives of many similar commercial programs like FL Studio. With LMMS, you can create an entire piece of music without having to insert a separate musical instrument.
