Welcome to the FluidSynth project Wiki


FluidSynth is a free software synthesizer. Its currently based on the SoundFont 2 specifications and supports real time MIDI effect controls. It can be used as a shared library for embedding in other applications, can play MIDI files and has a command line shell. Many other applications use FluidSynth for audio synthesis.


  • Cross platform support (Linux, macOS and Windows to name a few)
  • SoundFont 2 support
  • SoundFont 3 support (vorbis-compressed SF2)
  • Realtime effect modulation using SoundFont 2.01 modulators
  • Playback of MIDI files
  • Shared library which can be used in other programs
  • Built in command line shell

The Applications page has a growing list of other software which uses FluidSynth.

MadeWithFluidSynth is a page for users to post links to their Music and Audio creations made with FluidSynth.


The Documentation page contains information for both users and developers on FluidSynth.


FluidSynth currently has only a command line and shell interface which comes built in. Most users will likely want to use another application which interfaces to FluidSynth and provides a more friendly GUI.
