pyFluidSynth

Python bindings for FluidSynth

Copyright 2008--2024, Nathan Whitehead <nwhitehe@gmail.com> and others.

Released under the LGPL

This module contains python bindings for FluidSynth. FluidSynth is a software synthesizer for generating music. It works like a MIDI synthesizer. You load patches, set parameters, then send NOTEON and NOTEOFF events to play notes. Instruments are defined in SoundFonts, generally files with the extension SF2. FluidSynth can either be used to play audio itself, or you can call a function that returns chunks of audio data and output the data to the soundcard yourself. FluidSynth works on all major platforms, so pyFluidSynth should also.
