SFZ parser and synth c++ library, providing AU / LV2 / VST3 plugins and JACK standalone client, please check our website for more details.
Sfizz can be used most easily within an LV2 host such as Carla or Ardour. It can also be integrated as a library within your own program; check out our API bindings for C and C++. Our releases are an immediate way to get a working library or LV2/VST plugin, although you might prefer to build from source!
There is actually many things anyone can do, programming-related or music-related. Please check out the CONTRIBUTING document for information about filing bug reports or feature requests, and helping the development of sfizz
Sfizz and the work in the SFZ tools organization is purely driven by hobbyists who choose to use their free time to benefit this project. We firmly believe in the honesty and goodwill of users as a whole, and we want to promote a healthy relationship to software and to the cost of producing quality software.
No financial returns is explicitely required from using sfizz in any shape. However, if you feel that sfizz produces value for you or your products, and if you find that your financial situation allows for it, we put together ways to donate to the project. You are never compelled to do so, the CONTRIBUTING file contains different ways to contribute.
In all of sfizz's governance model, we strive to live in the open. Finances are no different, and we put in place a process so that the use of donations is as transparent as possible through our Open Collective. We invite you to check out the GOVERNANCE file to see how the organization is governed and how are donations handled.
