NFM

Note that NFM is in maintenance mode, receiving only critical bug fixes. For a more flexible and actively developed alternative, try Mela. It offers most of NFM's features as modular components and is frequently updated with new features.

NFM is an intuitive FM synthesiser with a streamlined interface. It works as an Audio Unit Extension (aka AUv3 plug-in) inside host applications such as AUM, Cubasis, GarageBand and Logic Pro.
