LMMS
What it is
LMMS is a free, open-source desktop tool for making music on Linux, macOS and Windows. It provides tools to create melodies and beats, synthesize and mix sounds, arrange samples, and sequence, compose, mix and automate songs. Notes can be played with a MIDI or typing keyboard, and projects can import MIDI files and Hydrogen project files. The software lists 16 built-in synthesizers, including emulations of the TB-303, Commodore 64 SID, NES, GameBoy and Yamaha OPL2. Multisample support covers SoundFont (SF2), Giga (GIG) and Gravis UltraSound (GUS) formats. LMMS supports LADSPA and VST effects, as well as built-in compression, limiting, delay, reverb, distortion, bass enhancement, equalizers and spectrum analysis. It supports 64-bit VST instruments, with a 32-bit VST bridge on 64-bit Windows, but does not support VST3 plugins. The manual says backups are enabled by default and a backup file is created when saving a project. The listed Free plan costs nothing.
