FluidSynth is a very powerful open-source synthesizer. Unfortunately for .NET developers,
it is written in C and has a very large API, much too large for Platform Invoking
each API. Therefore, the FluidSynth Wrapper for .NET wraps a large portion of the
APIs in managed classes. Although it does not give access to every feature of FluidSynth,
it does give access to the synthesizer, settings, and audio driver APIs in a very
.NET style class library.
You can get the latest release and source code for the FluidSynth Wrapper for .NET
from its CodePlex project site.
