A SoundFont Synthesizer

FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution.  FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps.


  • Cross platform (Linux, Mac OSX and Windows to name a few)
  • SoundFont 2 support
  • Realtime effect control using SoundFont 2.01 modulators
  • Playback of MIDI files
  • Shared library which can be used in other programs
  • Built in command line shell

New website

Welcome to the new FluidSynth website.  After SourceForge announced that it was discontinuing the hosted Trac service, I decided it was about time to give the FluidSynth website a makeover.  I added an Application Screenshots section which shows some of the applications which utilize FluidSynth.  Most of the other links on the navigation menu go to SourceForge services at the moment, such as the Wiki, where all of the previous documentation resides and continues to be user modifiable.  Bug and feature request tickets are now hosted on the SourceForge Ticket System.  Please feel free to Contact me if you find any issues with the website or have any suggestions.
