Summary

FluidSynth is a real-time software synthesizer based on the SoundFont 2

specifications. It is a "software synthesizer". FluidSynth can read MIDI events

from the MIDI input device and render them to the audio device. It features

real-time effect modulation using SoundFont 2.01 modulators, and a built-in

command line shell. It can also play MIDI files (note: FluidSynth was previously

called IIWU Synth).
