Wikipedia / LMMS

LMMS (formerly Linux MultiMedia Studio) is a digital audio workstation application program. It allows music to be produced by arranging samples, synthesizing sounds, entering notes via computer keyboard or mouse (or other pointing device) or by playing on a MIDI keyboard, and combining the features of trackers and sequencers. It is free and open source software, written in Qt and released under GPL-2.0-or-later.

System requirements

LMMS is available for multiple operating systems, including Linux, OpenBSD, macOS, and Windows. It requires a 1.5GHz CPU, 1 GB of RAM and a two-channel sound card.

Program features

LMMS accepts soundfonts and GUS patches, and it supports the Linux Audio Developer's Simple Plugin API (LADSPA) and LV2 (only master branch, since 24.05.2020). It can use VST plug-ins on Win32, Win64, or Wine32. The nightly versions support LinuxVST. Currently MacOS doesn't support them.

It can import Musical Instrument Digital Interface (MIDI) and Hydrogen files and can read and write customized presets and themes.

Audio can be exported in the WAV, FLAC, Ogg and MP3 file formats.

Projects can be saved in the compressed MMPZ file format or the uncompressed MMP file format.

Editors

  • Song Editor – for arranging instruments, samples, groups of notes, automation, and more

  • Beat+Bassline Editor – for quickly sequencing rhythms

  • FX Mixer – for sending multiple audio inputs through groups of effects and sending them to other mixer channels, infinite channels are supported

  • Piano Roll – for editing patterns and melodies

  • Automation Editor – for moving almost any knob or widget over the course of the song
