ZynAddSubFX is a open source software synthesizer capable of making a countless number of instruments, from some common heard from expensive hardware to interesting sounds that you'll boost to an amazing universe of sounds.

The project was started in March 2002 by Nasca Octavian Paul. He began to write ZynAddSubFX in order to create a synthesizer which could produce beautiful sounds, while being freely available to anybody who needs it.

This Project is now being actively maintained by Mark McCurry since 2009.
