A software real-time synthesizer (source files)
fluidsynth_source-1.1.11-3-source
Fluidsynth is a free open source software synthesizer written in C. It can convert MIDI note data to an audio signal using SoundFont technology without a SoundFont compatible soundcard. Fluidsynth can perform as a virtual MIDI device and read in SMF (.mid) files directly. Another function is its ability to send audio data to a Raw or Wave file.
